1: Use a game starter that routes different buttons to different paths. Bots ain't possible.
2: You can create story mode and arena (multiplayer) mode game in FPSC, although maybe you should stop playing timesplitters as mapmaking and challenges are useless/impossible
3: No, way far off from FPSC
Sorry, but FPSC is limited and is not really meant for fast-paced arcade games like Timesplitters. FPSC makes games like GRAW or Rainbow Six or Crysis, not Left 4 Dead and Timesplitters (although the single player version of TS would be completely possible in FPSC...)
