OpenTyrian2000 Enhanced v1.0-rc1

OpenTyrian2000 Enhanced v1.0-rc1 — first public release candidate

Tyrian 2000, the 1995 vertical shoot 'em up, on a new engine: Rust runs the game, Godot 4
draws it, plays the sound and reads your keyboard, mouse and gamepad. The campaign plays as in
Tyrian 2000; on top of it come an HD (AI) art mode, Endless mode, side modes and mutators,
achievements, five mod packs and a level editor.

This is a release candidate: the whole game is playable from start to finish, and we want your
feedback before calling it 1.0. Please report what you find on the repository's issue tracker.

Pick one game download for your system. The full downloads contain everything; the lite

Sizes in MB (1 MB = 1,000,000 bytes). SHA-256 checksums: see below.

• Windows: extract the .zip, open the OpenTyrian2000-Enhanced folder, run
  OpenTyrian2000-Enhanced.exe.
• Linux / Steam Deck: extract the .tar.gz
  (tar -xzf OpenTyrian2000-Enhanced-v1.0-rc1-linux-x86_64.tar.gz), then run
  ./OpenTyrian2000-Enhanced.x86_64 from the OpenTyrian2000-Enhanced folder.
  ./install-desktop-entry.sh adds a launcher with the Tyrian icon to your applications menu.
• macOS (experimental): unzip, then move OpenTyrian2000 Enhanced.app to Applications if you
  like. The app is not signed by Apple: the first time, right-click (or Control-click) it, choose
  Open, then Open again. If macOS still refuses, run
  xattr -cr "/path/to/OpenTyrian2000 Enhanced.app" in Terminal. Requires macOS 10.13 (Intel) or
  11 (Apple Silicon).
• HD pack: only for the lite downloads. Extract it into the game folder, so that
  upscaled/ sits next to the executable, then pick Setup > Graphics > Sprites > Remastered (or
  F10, Graphics: HD (AI)). Use the pack of the same version as the game.

Everything the game needs is in the folder: the Tyrian 2000 data (freeware), the MIDI soundtrack
and its SoundFont, the engine library. Keep the folder together. Your settings, saves, scores,
replays and mods go to a userdata folder next to the executable.

What's in this release

Downloads and your files

• The game, its folder and its executable are called OpenTyrian2000-Enhanced, and the
  release has lite downloads and a separate HD pack next to the full ones.
• Your files live next to the game, in userdata/: copy the game folder and your saves,
  settings, scores, replays and mods travel with it. A read-only game folder falls back to the
  usual Godot user folder.
• The Windows executable carries the Tyrian icon and version information; Linux gets icons and
  an optional desktop launcher.

Close to the original, screen by screen

• Mouse in every menu, as in the original: shop, Setup, saves, data cubes, two-player
  Arcade input choice and more. The in-level mouse speed matches the original, including
  on Windows with display scaling at 125 % or 150 %.
• Gamepad in menus like the original (LB confirms like A, RB goes back like B); analog
  movement is off on a new profile, as in the original.
• Level shortcuts of the original: F2 pause, F3 achievements, F4 statistics, F5 / F9 quick
  save and load, F6 DPS counter, F7 damage numbers, F8 sound on/off, F10 replay recording,
  F11 gamma, F12 screenshot. Outside a level, F9 / F10 open the Controls and Display screens.
• Record your own replays in game (F10) and play them back from the Replays screen.
• Episode endings as in the original: story pages, hint, name entry, high score table,
  credits, then the next episode.
• Secret level warps take you to the secret level.
• Fades, sounds, colours, the pause menu, the shop, the save screens, the end-of-level screens,
  Timed Battle, two-player games and the "Visual Effects" setting were checked screen by screen,
  so that each one looks, sounds and reacts like the original.
• Christmas prompt in December, as in the original.

Display

• Full screen by default, remembered between sessions; Alt+Enter switches cleanly; the
  window size and position are remembered in windowed mode.
• Fast start-up: no Godot splash screen, the title appears straight after the intro logos.
• In HD (AI) art mode the mouse pointer is drawn in HD too.

Modes and options

• Endless: every new run draws a fresh sequence of levels; the Endless leaderboard is the last
  page of High Scores; start it from Start New Game, or press 2 for two players.
• Side modes and mutators (M on the title screen) work in every mode.
• Achievements: all of them can be unlocked, with lifetime statistics kept in your profile.
• Modern explosions (Setup > Graphics > Explosions): shockwave, flash, streak and debris.
  The shockwave rings cool from white-yellow to orange to dark red, with a soft halo; small
  embers fly out of fire explosions instead of the original's hollow red sprite ring, fall
  slightly and cool down (with the original art they use the level's palette); a boss dies in a
  chain of 5 to 8 small explosions over one second before the final burst. Rendering only: the
  game plays the same, and the Original style draws the original's explosions.
• The CRT "Scanlines" filter looks like the original's.

Mods and level editor

• Mod ships, weapons, shields and sidekicks can be sold in the shop, with their own images;
  saves record mod items by name, and a save that needs a disabled mod shows a clear message.
• Five mod packs included, drawn in the original style and balanced against the original
  items of the same price: Alien Ship Pack (8 ships), Bio Ships Pack (6 ships),
  Alien Weapon Pack, Bio Weapons Pack and Elements Weapon Pack (6 weapons each,
  11 power levels; fire, ice that freezes enemies, lightning, rock, acid and wind). All five can
  be on together; they ship disabled: turn them on in Setup > Mods.
• Shots drawn by a mod are visible in levels.
• Level editor: undo / redo for added enemies, invalid mods are refused with the reason when
  exporting.

Languages

• The game is available in English, French, Spanish, German, Italian and Portuguese. The
  documentation, the package README files and the mod packs are in English.

Under the hood

• The game finds its data through a single place that also knows the layout of a macOS app; on
  Windows and Linux the data, mods and HD art sit next to the executable and your files in
  userdata/. The macOS download is a universal app (Intel and Apple Silicon), not yet signed by
  Apple.

Known issues

• Network play is not available ("Modem/Network Game" is greyed out).
• HD pack version: use the HD pack of the same version as the game.
