timespilliters is a good game if you have a friend to play multiplayer.
the thing that bugged me was that the game was made on compact disk. they focused so much on the multiplayer that they had no space for the actual single player. The single player mode is the strangest thing you have played ever, its where you run through the level killing enemies and collecting one item and then running back to the finish. on average you can finish each level within 2 minutes. so basicly you can finish the game in about 30-40 minutes depending what mode you pick. The only reason you should buy or rent this game is for the multiplayer. you actually create your own map and then play in it. A maximum of 12 players at once and a variety of guns adds some justice in buying this game.
So my advice is rent it first.
