TimeSplitters - PS2
Developed by some of the same folk that made GoldenEye and Perfect Dark, TimeSplitters was the first genuinely great shooter for the PS2. The game featured a story spanning over 100 years, which meant plenty of location variety and a wide selection of weaponry.
It was primarily loved for its multiplayer, which harkens back to the days of GoldenEye, in particular its frantic split-screen action. The game featured a colourful cast of 64 different playable characters, such as the wonderfully British Captain Ash, who says things like "Tally-ho" and Detective Harry Tipper, who looks like he's been ripped straight out of an American cop show from the 70s - complete with aviators and bushy moustache. You could also play as other zany characters such zombies, aliens, mummies, a gingerbread man and Duckman Drake - a man who was bitten by a radioactive duck... and turned into a duck.
Four on four battles took place on a total of 18 different maps ranging from Egyptian tombs and castles to onboard a spaceship and a Chinese restaurant; and you could play them in a variety of gameplay modes such as the classic deathmatch; BagTag, which sees players fighting over the bag to see who can hold on to it for longest time, Escort, where the players have to defend a bot from enemy damage and Last Stand, in which the player has to protect one or more objects from being destroyed from increasingly difficult waves of enemies.
TimeSplitters 2 was arguably the game that popularised the series and expanded on the multiplayer and took it to new heights, but the original is still regarded as one of, if not, the best shooters on PS2.
