Tyrian wiki sources and credits

Game figures come from the game's own data. History and background come from public sources, rewritten in our own words.

Game data

Prices, armor, damage, fire rates, enemy statistics, sprites, level routes, secret exits and boss lists are extracted from the Tyrian 2000 data files shipped with OpenTyrian2000 Enhanced (tyrian.hdt, tyrian1-5.lvl, levels1-5.dat, the .shp sprite sheets and palette.dat) by the wiki generator in site-tools/wiki-gen. Episode names, mutators, achievements and place names come from the game's English text files. The few enemy names the game itself gives (Ignatz, Morble, Meeble, Zimble…) come from its data cubes, matched to the enemy data by score and look; see the bestiary. Every name and its source is kept in site-tools/wiki-gen/data/official-names.json. Rules such as the upgrade cost, the energy system and difficulty scaling were checked against the engine's source code.

Controls, options and modding pages summarise the project documentation: the player guide, MODDING.md, the first-level tutorial, the data format specification and the level event specification.

External sources

• Tyrian (video game), English Wikipedia: development, releases, reception, open-source history and licences.
• Tyrian on the shmups wiki: release overview.
• Tyrian Wiki on Fandom: the community wiki of the original game, with pages on characters, planets and equipment. Its home page was used to cross-check the freeware and art-licence dates, and its level and boss pages for the names of most bosses (only the names: each one was matched to the boss the game data tracks in that level, and the source is listed on every boss page).
• Tyrian on Hardcore Gaming 101: the Game Boy ports and the Zanac connection, for the trivia of the history page.
• Vannevar's Tyrian page (archived): a fan site from the 2000s, used only for the Safari Software announcement in the history page's trivia, which is attributed to it there.
• OpenTyrian and OpenTyrian2000: the open-source ports this project builds on.

Forums, the original game, the soundtrack and other reference sites are listed on Tyrian community and resources.

• Sharp pixel-art filter: the xBRZ freescale shader from libretro's glsl-shaders (Hyllian, MIT; Zenju, GPL v3).

• Daniel Cook's remastered Tyrian graphics (Lost Garden, 2007): not used by the Enhanced Edition, which draws every sprite from the Tyrian 2000 data.

The licence notes for these files travel with the game in DATA-NOTICES.txt.
