Feel free to add Pepperpete to the Steam List. Looking forward to playing/eating/slicing some of you.
I've found the connection issues are now over and I've had a ton of enjoyable matches. But I must say that the 360 version looks terrible compared to the fully maxed PC version (tried them both). It doesn't even look like the same game details wise. Also I found it basically impossible to get trophies on the 360 but I can rack them up on the PC. Maybe it's the Mouse/Keyboard combo as I don't have to fight the controller.
So far I'm enjoying the Marine completely. Many people have complained that it's tough to win as the Marine but I really can't agree. On the controller I had difficulty hitting the Aliens but using the Mouse I can smack those bugs around no problem. Most of the matches I've played have had Marines teaming up instead of shooting each other. And Aliens trying to wipe out the marines etc.
It's funny but the rough launch of the demo (and don't kid yourself...it was rough) seems to have weeded out the MW2 twitch weenies (sorry if that offends.

) and left behind people who want to play like it's supposed to be played. Death-match was a terrible choice for the demo but it's giving me brief glimpses of just how great this game is going to be in the single player. The fact there will be 7 different types of multiplayer games is icing on the cake. Infestation is going to be the gamestyle I live on though (one person starts as an Alien, when he kills a marine that next person becomes an Alien and so on until it's last Marine standing).
But I have to stress this...the PC version looks a billion times better than the 360 version when it's maxed out details wise. If your system is a bit older then alot of the special effects probably aren't showing up properly.
My only complaint is the Smartgun noise. WTH where they thinking??? Everything else sounds spot on. Especially the motion tracker.
