I tried the multiplayer today, lots of fun. Managed to get myself a Geth Juggernaut, awesome piece of ass-kicking metal with a wonderful health-draining melee attack. Shame it's so slow, though given hardly anything seems to damage it I guess it doesn't matter. Ended up at one point alongside some crazy Krogan who went around smashing everything with a hammer, damn thing charged an Atlas and beat it down. I need to get me one of those.
