As opposed to CoD, which is camp, shoot, shoot, camp, camp, camp, shoot, camp, shoot, respawn?
It's probably telling that while I've stuck with the GoW series, I don't play FPS in multiplayer today, especially online, with so many cheaters. I've played Borderlands online as that is co-op, not competitive, and the only FPS I can think of I have played online deathmatch recently is Bioshock 2, as there were some achievements to go with the single player.
But if you get into the Horde or Beast modes, they're quite fun, challenging, and definitely not having to worry about uber 1337.
If people are around tonight, hopefully we can get five for the new DLC Horde achievements. That's about all I have left. I managed to fluke getting the "I Got This!" cheevo last night (kill ten as Guardian leader) as one round I was leader on with full teams lasted about 15 minutes! On Raven Down of all places. Man, that was an intense battle, probably one of the best games I've ever had overall.
