This game holds a special place in my heart. I was in my first or second university when it came out and spent many late nights playing multiplayer in my dorm room with friends (including the occasional game of drinking Halo).

Me and my best friend invented all kinds of games in the multiplayer, from mongoose jousting to sword only, invisibility and super speed.

The campaign was also great fun in multiplayer and the extra challenges you could add with skulls really added to the replayability.

It's just good ol' fashion shooty bang bang fun, you can't go wrong with it.
