Legend:

Base-game versions are structured like 99r#(b#)
NTT versions are structured like 100.###

100.034 (December 2025)

This is a u100 NTT build. It seems to run but I've not had time to extensively test it nor fix the 20-something NTT-specific bugs that exist.

Still, mods that worked in 100.033 should still work in 100.034, and maybe you'd like to see how u100-specific bits interact with mods.

The last NTT build has been archived onto the "ntt_u99" branch.

100r7 (December 2025)

Fixed a mystery crash on boot if your save file is weird

Rad attraction:

Classic rad attraction mode is now the default (ID 0 or 1)
Modern rad attraction mode is now ID 3
Fixed some modern rad attraction code leaking into classic
Further fixes for rads getting stuck in modern rad attraction mode
Pretty much every improvement to modern mode makes it harder to "rad starve" so that's why it's no longer the default

Unlocks:

YV B-skin condition now correctly considers Cuz; can be awarded retroactively
Fixed Fish B not counting Cuz and counting secret chars

Custom mode:

Custom mode with Ultra Start no longer leaves Skeleton without ultra mutations; fixed Skeleton A not accounting for maximum level in custom mode
seed.txt no longer overrides a custom mode's seed
Storing a "no weapon" in a proto chest in Custom Mode now hands out a rusty revolver

Visuals:

Fixed display timer counting fractions of seconds incorrectly
Fixed allies spawned by Rebel ultras not applying C-skin
Speedrun timer no longer draws over unlock popups
DAILY/WEEKLY/CUSTOM label on the pause menu no longer draws under the portraits
Chicken C now uses black feather particles
Fixed Throne II missing "II" in UA/RU locs

Audio:

A shot-in-the-dark fix for music randomly stopping mid-level.
Believe it or not, but this is pretty hard to re-create on purpose.
Fixed Lil Hunter music not stopping on one occasion

Settings:

21:9 aspect ratio with previously-auto setting will be reset to 4:3 one time not to confuse people
Weapon/mutation tooltips will be set one time to upgrade u99 settings (where they were off by default)
Added experiments>show_swap_for_everyone if you'd like those little weapon-ammo popups on other chars and not just Cuz

Misc:

Fixed the game crashing on main menu if your settings file is sufficiently malformed
Stripped some unused DLLs from the build

100r5 (December 2025)

Gameplay:

Cuz experiments:

Cuz:

Fixed it not being possible to pick up a non-cursed weapon as Cuz when your weapon is cursed but you still have 3rd+ weapon slots
Fixed repeated gold weapon popups when a gold weapon is in Cuz extra slots
You now only gain tears as Cuz if you took non-zero damage

Cuz experiment:

Added an experiments > cuz_swap_mode to settings JSON that you can flip to 1 for an alternative swap mode.
Swap+1..6 sets a hotkey for the weapon slot (e.g. Space+1 on default keybindings)

This may get removed later if it doesn't feel good.

Fixed Cuz B hint using the wrong color, and in some languages, wrong font style
Fixed Cuz/Cuz B achievements not being awarded (will award retroactively)
Fixed the game not transitioning to 2-x in Custom Mode if you've set the area size higher than 4
Fixed the game crashing upon entering the main menu if your save file exists and isn't empty, but is filled with 00 bytes instead of save data
Fixed Horror C unlock still being easier than intended
There's a secondary issue being that the hint says "with no more than 3 mutations" while the unlock says "without reaching level ultra" - we'll fix this later
Some Ukrainian localization tweaks ft. Ci8ird
Fixed the game crashing if you perish on the exact frame when Lil Hunter takes off

100r2 (December 2025)

Added a backup unlock check for Cuz
There is as of yet no explanation as to why this broke only in release build
Fixed present ammo chests not playing their "open" sound
Fixed being able to select C-skins in co-op when you only have a B-skin
Dog Missile (which is unusable unless you're Big Dog) is no longer on the custom mode weapon picker
Adjusted unlock conditions for Eyes C and Steroids C to work even if you go beyond the intended spot
Adjusted unlock condition for Steroid C to allow starting with a golden weapon
Fixed Eyes C portrait being a little out of frame

100r1 (December 2025)

Note: u100 NTT build is coming soon!

The important:

New character: Cuz
On NTT terms, the character still uses the original placeholder character ID, but everything else is new; Cuz can no longer be chosen as a ""C-skin"" for YV in NTT.
Custom Mode
CM allows to adjust a handful of game parameters without modding the game.
Mods can change these dynamically using UberCont.custom (enable/disable) and UberCont.customMode (custom mode struct)
The game now supports up to 4-player local co-op.
Also features improvements to co-op ultra mutations and co-op menus.
Co-op reviving has been reworked and now works with Revive Chests.
In NTT, previous reviving is accessible using /revmode u99
New unlockable C-skins for every character (and new achievements for these).
In NTT, this shifts community skins to D-skins where appropriate.
Localization for 15 languages: English, French, Italian, German, Spanish, Polish, BR Portuguese, Russian, Korean, Simplified Chinese, Traditional Chinese, Japanese, Ukrainian, Turkish, & Dutch
Community localizations can also take advantage of new options in lang.ini and support for CSV languages.
Reworked and re-organized the settings menu.
In NTT, new settings can be accessed through the UberCont.opt struct.
Existing settings are kept as UberCont.opt_* for backwards compatibility.
New side art and a new cursor.
The game now has a modern Mac version, compatible with Apple Silicon.

Smaller tweaks:

Buff gators may once again pop out of cocoons, but more occasionally than before
Open Mind has been buffed a little.
The game now runs better on Steam Deck.
The game now works better with gamepads, especially when multiple are connected.
Added 16:10, 21:9, and automatic aspect ratio options.
The game now runs at 60 fps by default.

100.033 (July 2025)

A few more tweaks to 3d audio; the scripts are now included for reference in this repo.
Fixed the weapon pickups sometimes rotating in place when there's a bunch of them in one spot.
Weapon pickups are now less likely to get stuck if they were spawned from a chest next to a wall.
Weapon pickups now push each other around a tiny bit stronger so that they overlap less.
Fixed Ultra Mutant achievement not granting on load if you're past 100% completion.

100.032 (July 2025)

Mod scripts can now have optional arguments (function name(a, b = 1) {})
Fixed loc / loc_set in mod API

99r2b26 (July 2025)

The game now lags visibly less when the stage has been dug up before a T2 fight.

100.031 (June 2025)

Exposed and documented dp_player_count_active, dp_player_count_sources
Fixed ds_list_shuffle

99r2b25 (June 2025)

I (YAL) now appear on the "Vlambeer & ... present" screen, which might reduce the number of people asking JW to hire me to work on this game despite me working on this game since 2017.
You can now skip the intro screens by clicking when gamepad controls are enabled.
The credits screen has been overhauled:
- YYG Special Thanks pages have been merged into the rest of Special Thanks
- Special Thanks page now starts partially on-screen so that you can tell that it's not just an empty page
- You can now scroll the Special Thanks screen with up/down keys
- Ada (the other half of ThroneButt development team) is now credited
- lang-example now only includes parts of credits that make sense to localize instead of large blobs of text
Fixed the game crashing if your Steam avatar is a broken image (??)
Fixed "(golden weapon) stored!" notifications showing repeatedly.
This one's quirky because it would only happen when making a release-mode build with optimizations enabled.
Fixed the timer not showing on Game Over screen when using the "Both" timer mode
You can now pick the random crown in loadout (when you have 2+ crowns unlocked)
Fixed some input oddities with loadout when using gamepad+mouse controls

Fixed a crash when loading custom mini-font in localizations

NTT:

CustomProp now has an on_draw callback

99r2b23 / 100.029 (June 2025)

Voting for /ultras all + own will now pick own
Space is now allowed as "swap" shortcut in menus and hopefully that doesn't break anything

Fixed walls on 0-1 not making debris/sounds when destroyed.

Fixed mods misbehaving due to a YYC optimization
Fixed surface_create, ds_map_keys_to_array/ds_map_values_to_array, background_color

100.023 (May 2025)

Most of the work behind this update is invisible because I'm updating the scripting system and migrating documentation to GitHub.

Additions:

Player now has grant_health and grant_ammo methods that you can override in custom races to change how healing/ammo gain work. (this also eliminates a bit of copy-pasted-but-slightly-different code, e.g. from LilHunter vs enemy)
Added support for fast_file, not_fast, and no_using pragmas
Added char_custom
Added move_and_collide
Added instance_nearest_nonself

Fixed /gmlapi crashing the game or not logging the assets to files
Fixed #pragma using not working for mods that are being loaded together on one frame.
Fixed string_split_list, which I don't think anyone used for a while now.
Fixed mouse_x_nonsync and view_xview_nonsync missing an array specifier
Fixed NTT add-ons to some functions (like drawing visibility) not applying

99r2b21 (May 2025)

This build is unreleased at the time of writing this, but changes from it are in NTT 100.023 so it kind of needs to be here. It'll be pushed as soon as it is confirmed that the game doesn't randomly catch fire.

Additions:

One new Melting loading screen tip
Anniversary cake returns (on Dec 5 each year)

Fixes:

Fixed a seemingly-impossible crash with gamepad aiming
Fixed WaterMine bullets not being affected by Euphoria
Fixed RoguePickup creating RabbitPaw effect even thought it doesn't do anything for it
Fixed Tangle briefly panning camera on new throw
Eating weapons as Robot now doesn't grant health when you have CoLife instead of (incorrectly) CoDeath
Fixed hyper slugs never resetting their +1 bonus damage
Health chests created by Regurgitate can no longer break walls
Allies and Saplings are now affected by Impact Wrists, but you might hardly see a difference
Fixed type-based SubAmmo:# localization key not being supported
Fixed stick swap on gamepad not swapping the aim stick
The game should run on Windows 7 again. If it doesn't, please report with error message(s).

99r2b20 (February 2025)

Changes:

I'm doing another experiment with how close-by audio plays, perhaps this one will be true-est to original
On L6 and later, the game will now slightly simplify how enemies collide with each other and bounce off walls. This brings a minor performance improvement
Boiling Veins now also applies to player-created flames and flame shells

Fixes:

Fixed "self is not an instance" popping up when calling specific functions.
With execution order hopefully back to original, more mods should function normally.

99r2b19 (December 2024)

Changes:

To make the game work closer to how it did before, I changed all of the step events to be user events that the game runs from a script.
Functionally everything should be working as normal, but let me know if you spot any entities not doing their job.
Mouse lock now only applies mid-game, not in menus.
I tried to make the audio work like it did before, but it's still kind of weird, so you can now add the following section to NuclearThrone.ini
```
[snd_play_hit_big]
min=320
max=64000
cap=320
```
and play around with values.

Fixes:

NTT-specific documentation no longer ends up in NT builds.
Clicking during heavy lag should now be buffered.
"Fish digging" should now be harder to pull off
(but the logic stays in case you really get stuck in a wall)

99r2b18 / 100.020 (December 2024)

Fixes:

Custom localizations no longer show "ALWAYS BELIEVE IN YOUR SOUL" in place of many strings
Fixed weapons playing various ambient sounds instead of their swap sounds
Fixed a handful of ultra mutations not working correctly
Fixed character select using the in-game fire/confirm button instead of the fixed one from the menus

100.019 (December 2024)

Changes:

With 2024.11, GM now assigns resource indexes alphabetically, which means that hard-coded resource indexes might no longer behave like they did before.
As one exception, I gave Player a __PlayerParent parent object so that you can still do /gml =0.x and alike for quick tests.
If you replace the spiral sprites, the HD spirals (that are used when pixel scale is over 2) are now correctly colored
Added key0 input for sake of completeness

99r2b17 (December 2024)

Changes:

Updated to GM IDE v2024.11.0.179 / Runtime v2024.11.0.226!
New GM version changed how 3d audio works but I think I got it to act the same as before.
There could be other differences in behaviours, but hopefully not.

Controls:

Probably fixed fish digging
Sniper laser sights are now lighter on performance

99r2b15 (December 2023)

General:

Fixed (?) a mystery crash when unlocking crowns
This is the same kind of thing that was previously causing a crash with ultra mutations and I do not like the implication that it's now unsafe to work with 2d arrays.
Updated lang-example.ini
Fixed unlock popups not appearing
You can now add more tips to categories in the language file and they will be picked up.

Thrown gold weapons now sparkle correctly when localized (and make the gold pickup sound)

NTT:

Fixed there being an extra GameCont in NTT character select

100.016 (December 2023)

General:

It is now cheaper to destroy walls, both for the game and for the mods.
On the technical side, FloorExplos now avoid creating walls on top of other walls (which are immediately destroyed), and explosions/portal objects queue walls for destruction by UberCont in end step (which further avoids creating instances that would be destroyed right away).

Modding:

Fixed wrong sound names being reported for external audio files
(for sound_get_name and asset_get_index)
Laser/lightning sprites now have "rotated rectangle" bounding box type in case you want that instead of the default bounding box

Fixed replaced music/ambient sounds not taking effect

Steam multiplayer might work now (but I don't have a setup to test it)
There are also changes to how files are sent, which might improve loading times for big packs
OGG audio files now sit in amb/snd/mus subfolders
Textures now sit in tex folder instead of being embedded in the executable, making them easier to mod
This is also currently causing placeholder textures to be briefly visible as the PNG file loads, but I'll figure it out later

Modding:

Fixed [@] accessor
[$] accessor is now disabled for GMLv1 mods

100.010 (june 2023)

General:

Hopefully fixed the issue with the game randomly not starting (by updating both GM and Steamworks extension)
Replaced the borderless fullscreen implementation by now-built-in functions

Netcode:

Online multiplayer works again, for now in UDP mode only (Steam's in the next release)
Replaced now-incompatible FaucetNetworking DLL with a very tiny UDP wrapper (IPv4 only, no hostname resolution)
Probably fixed the crash on desync, which means that you can hunt the elusive scrapyard desync with /tracksync again

Modding:

Scripting language is now mostly-on-par with GM2023.4 syntax features
Shuffled some things around to hopefully cause less stress on the garbage collector when working with huge mods
Added some string and array functions from GM2023.4
Added zip_unzip (unzips for the player calling the function, both zip and destination are relative to the mod's data folder)

Fixed golden nukes not following the cursor after 100.x changes.

Modding:

The scripting language is now updated with most of the recent GML additions such as static or 100_000
Added array_filter, array_map, array_reverse, variable_struct_filter, variable_struct_map
Removed the recently introduced object_* manipulator functions due to excessive volatility
Added event_perform_object
File-related functions are now aware of mod file's relative path
Added mod_current_path, mod_current_dir; file init order is now predictable
Added Player.calc_pickup_attract_distance() and Player.calc_rad_attract_distance() (which you can override with your own functions)
Added CustomPickup
self/other now return an ID in GMLv1 mods.
Since the game now runs on GM2022.11, IDs are now a ref type, but we'll pretend that they aren't for GMLv1 mods.
Projectiles now have a creator_projectile variable for tracking submunitions
Race mods can now define a race_gets_chilly script.
Race mods can now define a race_makes_air_bubbles script.
Area mods can now define a area_set_music script.
Fixed instances_in_rectangle/instances_in_circle not working with array arguments
Fixed on_ script ID->script binding conversions being too generous (and applying when writing variables to objects that didn't use to do conversions)
New-format menus now create a single dummy button so that mods making use of instance_exists still work
GMLv1 mods are now allowed a bug where you can do [1 2 3] instead of [1,2,3]
Added projectile.portal_immunity
Mod errors no longer show the ultra-verbose call stack by default; original behaviour can be enabled using /debugstack
I updated most of the game's extensions, but that doesn't necessarily mean that multiplayer works now

100.006 (july 2022)

Mods can now have a .ntgml extension to default to v2 syntax (so that you don't have to put #pragma gml 2 in each file)
Included code files now run their init too, although not in a fancy order (for now)
surface_free used in v1 mods can now take -1 or non-surface args again
Fixed initial Vlambeer logo being off-center if you specified non-4:3 aspect ratio
Fixed weapon scripts not getting self/other when called through weapon_* by another mod
Fixed alarm# not working for structs
Fixed sprite_skin() not getting self
Fixed mod-loaded sprites defaulting to 30fps instead of frame-per-frame speed

100.005 (july 2022)

General:

Fixed a crash in scrTarget
There's now a "mechanics" menu in the "game" menu where you can change rad attraction mode, framerate, and aspect ratio

Modding:

Framerate/aspect ratio settings now auto-load in NTT
Fixed try/catch not being available in non-gml2 mods

100.004 (july 2022)

Modding:

PhantomBolt now has fadespeed and also doesn't move
Fixed instance_in_rectangle/instances_in_circle returning undefineds
Game no longer crashes if a mutation/ultra button sprite is unloaded
race is now consistently a string and race_id is consistently a number (I'll see what to do with Revive that had them swapped later on).
is_object now returns false for ds/etc., added is_builtin for those.
Added #pragma fast - can be included in a script to compile it in alternate mode. Generally ≥2x faster, supports ~2/3 of GML syntax, may struggle with specific features.

100.003 (june 2022)

Modding:

real(v) now behaves like the GMS1 function (doesn't throw errors), GMS2.3 real is double(v)
Fixed some resource-related functions throwing a cryptic error when ran on an nonexistent file
Fixed the game crashing if unloading/reloading a character mid-level-gen
Making a mod unload itself no longer crashes the game (nor will unloading some other mod and then managing to run a function from it)
PopupText now accepts both mytext (actual variable) and text (legacy alias)
Fixed ++alarm0 / alarm0++ ignoring variable rules
Fixed race / race_id variables not working right
Fixed background_color setter not doing anything

100.002 (june 2022)

Modding:

Fixed Quick Restart switching players to Random
Fixed is_real, for real this time
Fixed non-GMLv2 mod functions sometimes returning undefined instead of 0 by default
Calling built-in functions should now be a tiny bit faster
Array literals ([...]) now use argument list optimisations from function calls
Fixed #macro name { "key": / #macro name { key: being mistaken for a malformed code block
projectile_hit_raw is now marked as an instance-specific function since it accesses other for lasthit
Mod dumps (from /debugbc) now include slightly more info (local variable IDs, local variable names in corresponding instructions)
I tried making use of the 2.3 delete keyword to help GM garbage collector free mod function invocation leftovers sooner, which will either slightly help performance or cause the game to mysteriously crash

100.001 (june 2022)

Modding:

Fixed broken signatures for method and lq_get; added checks to make sure that I don't do this again
NTT is now back to using LCG RNG since people relied on rewinding RNG seeds
Fixed ds_list_shuffle
Added more special cases for function argument chain optimisations (now supports constants, local vars, and self/current instance vars)
Added #pragma using modname.type (e.g. #pragma using sprites.mod) that automatically makes top-level functions and globalvars from the said mod available in the current mod similarly to (but more optimised) mod_* functions. The mod in question should be loaded before the mod using it - references are collected compile-time.
You can now do globalvar name = value
Added /gml2 command for doing new-syntax snippets
You can now add an empty no_intro file to game or save directory to auto-skip intros
Fixed a crash when exiting a session after using object_add
Player now sets aimDirection on fire/step so that a few mods using that variable are less likely to break
Melee projectiles now have a shared meleeprojectile parent.
Swapped race / race_id back for Player, CharSelect, and EGSkillIcon
You can now reference "built-in" functions again (var t = trace; t("hi!"))

100.000 (june 2022)

Modding:

Rewrote some of the checks that would be causing issues when used together with object_add
Player now has swap_weps() and calc_reload_speed() that you can call or replace
Fixed current_time_scale being non-writable
Framerate option won't show up in NTT for now
lq_get/lq_defget will now return undefined for non-structs like it did before (variable_struct_* is unaffected)
Added current_time_scale_squared that should be faster than squaring it yourself (game code also uses it)
Added missing accessors for some timescale-based variables
Fixed area_can_spawn_portal, weapon_get_list
method(newSelf, func) is now available
Fixed instances_matching_ne putting instance-structs into array
Seeding-related variables can now be found in GameCont again
/gml errors no longer show \ns
Fixed new / function not working with #pragma gml 2
Instance variable errors are now more descriptive
crown_get_pick / crown_set_pick now use 0 as "default" instead of -1
collision_line_point / collision_line_width_first now return a struct and take an optional struct argument to populate
Fixed some API functions working strangely due to using a wrong self
ultra_count now returns a dynamic value for Skeleton
Fixed some instance functions not working due to legacy NTT implementation overwriting the new one
Booleans should now be booleany (as far as type/print go) more often
instance_is should no longer throw an error for destroyed instance IDs
Fixed chat_comp_add adding first argument to rest-arguments
Projectiles now have sprite variables (spr_dead, spr_disappear, spr_impact - depending on the thing)
Fixed modded loadout weapons showing sprite#0 for struct-weps

100.x in nutshell

The game has been migrated to a current GameMaker version (first GM2022, then GM2023).
The scripting language was more or less rewritten from scratch to be more performant and have more features.
Hopefully we're back to having functioning online multiplayer in NTT?
