I need practice on Deep Freezer, I suck using it. I'm abusing the hell out of the motion sensor since you mentioned it.
I like Fumigation now, its sorta like Domination. Used to do TDM solely. Not I'm digging both game modes. The other game mode with the Battery is tough.
I cant stop using Dawn Patrol, gotta be a better gun(s).
Game starting to get addicting for me.
