Good game! Connecting to the online game was pretty painless. I think it was Mr2Fa$t who had to point out to me that you had to press ESC to join in. It's an impressive and well made game. Nice creepy christmas music. Loads of weapons, different looks for your main guy. In that respect it beats COD, where you always have to play as the same boring dude.
My connection appeared to be pretty laggy. I imagine that's down to my PC. I don't usually play multiplayer on PC.
I think it would be cool to have WASD as well as arrow keys, but now that i say that, maybe it's in the options.
I tried picking the guy with the snow camo, but still got shot way more than i shot other people. Need practice i guess.
Haven't figured out how to use the jetpack or do the special moves yet. Jetpack is a genius idea BTW.
