One of the greatest games ever! Throw away your television and play this game!
The advent of capturing the spawn points make sure the game flows back and forth giving it the real feel of a battle for territory. Single player is lame but really only necessary for practicing to go online. Once you are online you may want to spend some time finding a server that suits you as you get wiped out as a beginner on some of the more popular servers. This doesn't happen for long as you soon figure out how to stay alive. Friends, joining a squad, team mates and medics make it possible.
I highly recommend buying this game and quitting watching TV!
