v0.5.0 — final (Godot port frozen)

Final release. This Godot port is frozen as of 2026-10-13 and is no longer developed. Development continues in a new C# + SDL3 port, to be published later.

As before, the builds carry no game data: they read your own copy of SkyNET (and optionally Future Shock).

Changes since v0.4.1

• Future Shock takes SkyNET's palette as the original does; the moon has DOS's size, shape and place.
• The jeep turret turns the full circle; the HK has only DOS's flight ceiling.
• Staged cars keep taking hits on their last frame and burn out, as in DOS.
• Bots react after their skill's full reaction time and lose a target they cannot see.
• Robots stand where the original stands them (no more turrets sunk into the ground).
• Footsteps per map surface, landing sounds, pain grunts and the death grunt; drowning and radiation hurt silently.
• Sound mixing as in DOS: at most six placed sounds and six nearest loops at once.
• Robots look every 4th tick with DOS's distance; a hit alerts them until their next look; turrets fire without a line-of-sight check.
• Game sounds pause in the menus.

v0.4.1 — Future Shock playtest fixes

Builds for Windows, Linux, macOS and Android. As before, no game data is included: on first start the game asks for your SkyNET folder (and, optionally, your Future Shock folder).

Future Shock

• Leaving a building puts you in front of its door, not back inside its walls (the gas station, the hotel; #5).
• The player is as wide as in DOS, so the hotel's half-open door can be passed (#4).
• Spider robots walk instead of treading on the spot, and robots walk indoors as well as outside (#4).
• Future Shock starts from SkyNET's NEW GAME menu with its own briefing, as DOS starts it.
• MAP.050: the canal entrance on the way to the HK can be used.
• MAP.060: the camp's objective is met when its defences are destroyed, as in DOS. A game saved in mission 60, 90, 110 or 120 before this release carries the old objective count: restart that mission.
• Future Shock finds the 640×480 hi-res HUD set.

Both games

• Closed doors are solid: you can no longer run through one and fall out of the map. The use key reaches a doorway's exit even when you look at its gate.
• Low sills under low roofs are steps, not walls; chairs can be stood on again.
• Every flat-coloured face has its own colour (some showed the wrong one).
• The night sky has the original's stars, and outdoors the world ends where DOS ends it, at the view distance of the DETAIL setting.
• Hints and objectives are typed into the panel's message box, also in the enhanced HUD (bottom right).
• Hold RUN while firing a rocket to ride along with it, as in DOS.
• Each thrown item (molotov, pipe bomb, grenade, canister bomb, satchel) has its own look, blast and sound; the pipe bomb and the canister bomb bounce.
• Jeep: the gun looks 45° up and down, and the reticle is sharp at any window size (all vehicles).
• HK: it flies under the original's ceiling, and a hill can no longer lift it over a barrier.
• F12 toggles a test overlay: frame time, the mission's objectives, and an arrow to the next one.

Notes

• macOS: the app is not notarised — right-click → Open the first time, or run xattr -dr com.apple.quarantine SkyNET.app.
• Android: a debug-signed APK for sideloading; allow installs from unknown sources.

v0.4.0 — Future Shock, missions as scenes, Android

Builds for Windows, Linux, macOS and — new — Android. As before, no game data is included: on first start the game asks for your SkyNET folder (and, optionally, your Future Shock folder).

Future Shock

• NEW GAME → FUTURE SHOCK plays the Future Shock campaign on SkyNET's engine, as the DOS game did.
• Its own 17-mission campaign, vehicles and start kit (the pipe alone), read from the original tables.
• Side maps are walked, not driven or flown (MAP.103 and MAP.129 no longer trap the player).
• Future Shock's triggers now follow the same, checked rules as SkyNET's.

SkyNET

• Missions are played one scene at a time; each map keeps its own state, and only the dead and what you picked up carry between visits, as in DOS.
• Doors, lifts, gates, lamps and switches work the way the original opens them, including floor switches you trigger by walking over them (the MAP.210 silo cover, the MAP.215 cover).
• Nobody swims: in water you walk on the bottom at half speed, and the water is see-through.
• The submarine's torpedo tube carries you through the water into the sewer, as a ride.
• The convoy on MAP.260 drives at its original speed and does not wait for you; the truck and helicopters follow their paths.
• Ammo you have left carries into the next mission, and a won mission tops it up from the original per-mission table.
• Movement speeds, player damage, the DOS status panel, the jeep's turret aim, the five throwables (F1–F5) and RESTART MISSION follow the DOS game.
• Fixed: the mission 1 ending, the MAP.217 gate, the MAP.271 tunnel teleport, the MAP.252 return trip, explosions that sometimes didn't show, texture seams with smooth textures, and the debugger warnings on start.
• Deathmatch: the host owns the map, triggers sync to every player, and bots count in the score.

Mods

• A map can be replaced by a Godot scene in mods/maps/MAP.NNN.level.scn (see COMMANDS.md).

Notes

• macOS: the app is not notarised — right-click → Open the first time, or run xattr -dr com.apple.quarantine SkyNET.app.
• Android: a debug-signed APK for sideloading; allow installs from unknown sources. Not yet tried on a device.

v0.3.0 — no game data in the builds, and a hardening pass

The builds carry no game data. v0.1.0–v0.2.1 accidentally packed the converted asset cache into the executables; those releases have been withdrawn. As before, the first start asks for your own SkyNET install (and optionally Future Shock) and converts the data once.

Upgrading from an earlier build

• The asset cache is rebuilt on the first start (new cache format). A full conversion takes a few minutes; maps you have not visited convert when you load them.
• Saves: old saves still load; new saves use a new, safer format. Future Shock keeps its saves apart from SkyNET's.
• Multiplayer: everybody in a match needs v0.3.0 — the join handshake changed, and an older build cannot play with a newer one. From this version on, a mismatch is refused with a message instead of hanging on Connecting…

Fixes

• Home, Page Up and Page Down (the default look keys) no longer jump to another map mid-mission.
• After a won mission the cursor is back on the briefing screens and in the menu.
• A save remembers which map the mission started on, so loading one can no longer skip a mission; saving is refused during the mission-complete countdown.
• Revisiting a map no longer repeats its objectives, radio lines or water level changes.
• One map change at a time: pressing keys during a fade can no longer break an exit.
• The CONTROLS screen can bind mouse buttons again.
• RENDER DETAIL, smooth textures, dynamic lights and the 640x480 weapon art apply immediately.
• An exit that cannot be used no longer disables every other exit on the map.

Deathmatch

• The motion detector marks nearby players the way the original does: a dot, the player's name and the range in metres.
• Bots score their kills; a jeep is freed when its driver leaves or respawns.
• The host checks hits, positions, pickups and vehicle use, limits message floods, enforces kicks, and the console cheats are off in a match.
• The LAN server list only answers local networks.

Performance

• Enemies check the ground and their line of sight less often, effects reuse their nodes and materials, and shaders are warmed up behind the load fade: frame spikes on the big outdoor maps are roughly halved.
• The first-start conversion is about twice as fast.

Robustness

• Cached files and map mods are loaded only when this installation wrote them, or when they pass a data-only check.
• Damaged or crafted data files can no longer hang the game or exhaust memory.
• Data copied with lower-case file names is found on Linux.

Platform notes

• Windows: a single SkyNET.exe.
• Linux: chmod +x SkyNET.x86_64 after downloading.
• macOS: the app is built on Windows and only ad-hoc signed. Open it once with right-click → Open, or run xattr -dr com.apple.quarantine "SkyNET Godot Port.app".
