Raptor: Call of the Void

A web remake of the 1994 MS-DOS vertical shooter Raptor: Call of the Shadows (Cygnus Studios / Apogee / Scott Host). Moved theme to space and redrawn with modern procedural art and sound. Logic, weapons, enemy formations, and flight paths are ported 1:1 from the released DOS source code.

pnpm install
pnpm dev          # http://localhost:5173/raptor/
pnpm test
./scripts/run_checks.sh

Game data (maps, enemy tables) is inspired from the shareware release. Graphics and sound are newly generated (no original assets are shipped):

# download FILE0000/0001.GLB from https://archive.org/download/RaptorCallOfTheShadows/raptor.ZIP
# to original_game/shareware/ (see original_game/README.md)
node original_game/scripts/extract-glb.mjs    # regenerates src/game/data/ep1.ts (+ original audio archive)
node scripts/gen_audio.mjs                    # regenerates public/assets/{sfx,music}

Review pages (dev server only): http://localhost:5173/raptor/review/art.html (all sprites, enemies grouped by mission) and http://localhost:5173/raptor/review/sounds.html (new sounds next to the archived originals).
