I'm not joking, if you like Multiplayer, buy this game.
So why such a high score? Well let me tell you. After two years, me and my best friend haven't put this game down. No Joke. You create a profile, and every match you do, all your stats are saved to this profile. So after countless matches we can look at our scores, and see just how well/crap we're doing!
Not only this, but when you create a bot, the bots stats are also saved! And the more kills the bot has, the more you can upgrade him/her. Our current bots are Old Git, Andy, Zombie X, Goat Man are Ghost, and their pretty maxed out.
Frankly, although the graphics aren't unsurpassable, this game is a MUST for anyone who likes multiplayer and shooting games, and remains to this day one of my favourite games on PS2. Simply put...Buy it!
