#19 - Timesplitters 2 (PS2)
As guessed by no-one!
Timesplitters wasn't a series I stumbled into myself like many of the games I play. It was introduced to me by a friend who insisted I play the multiplayer with him, which I did, and instantly became hooked on the fast action, OTT gunplay with a zillion customisation options. I went out and bought the game myself to discover a ridiculously satisfying single-player campaign combined with so many options for offline bot play and even more options for local multiplayer. To this day, my friends and I still break out Timesplitters 2 for some virus gameplay on Mexican Mission. God, I love this game.
