Left 4 Dead 2 is one of those games that doesn't come around very often. A great coming together of various game modes that has created a film-like multiplayer experience that focuses more on teamwork than of the one-man army. In the day where other shooters are trying to add some type of team-work element to their basic game modes, the Left 4 Dead series takes small team games to the next level of intensity. Of course there are glitches, as in any game, but since the game is so based on high-important single-action moves (i.e. "setting up"), exploits and griefing can be frustrating during an hour-long game. But there are so my options, can just go play campaign on expert, maybe add realism, play friends-only games, do scavenge or survival. There are many options, and if you can avoid the griefers, the Left 4 Dead series is one of the best games. I can't wait for L4D3, but that's another matter. Ending, if you don't have this game, get it. It's worth the bones. (Update: Back 4 Blood came out, it's not L4D3, guess I'm back to waiting.)
