I can't wait to never play Infection again once it's moved out of Rumble Pit. It kept coming up when I was trying to get some challenges today and I just wanted to rage. I honestly was enjoying it when the game came out, but after a month of it coming up waaay too often, I just can't stand it.
It really sucks on certain maps (Asylum when the Spartans get on top of the cliff, or the top level of Zealot), but The Cage is especially bad. All of the Spartans can just hang out in the enclosed middle area where they spawn, have a clear view of nearly the entire map, and just annihilate the zombies from a distance with the magnum.
