Half-Life 2 - CSS SCI FI v2.1

CSS SCI FI is a single-player Half-Life 2 mod which puts the player through 27 intense combat missions set in Counter-Strike: Source maps. Each map contains a unique scripted scenario which is enhanced by random scripting so that the game is never the same twice. Players will fight everything from Striders to slave Vortigaunts, plus a range of Combine enemies armed with many new weapons. The v2.1 is now locally mirrored (thanks: Blues).
