The Vanilla+ Mod recreated for PS2 players of TimeSplitters 2.
Instructions are included in the README file on how to patch the PS2 version of TimeSplitters 2 - it's not the same as the GameCube version. Most of Vanilla+'s GameCube features make it into this port, although I could not find how to unlock MapMaker Story co-op and increase the allowed spawns for Story maps. Both versions of the mod unlock all characters by default.
