Only things I really hate are the melee system, the explosion range of the normal grenades and how the DMR is just not a good weapon compared to the Needle Rifle and the Pistol.
Also, the only overpowered armor ability I've seen so far is the Cloaking one. It's really hard to just win after someone that has it even if you start attacking him at the same time that he sees you (because of how the melee works, you'll mostly die at the same time as him, Halo 3 double KOs style!).
I'm enjoying this new ODST beta compared to the Friends & Family one. People in that one were just toooo good. I mean what's the point, it's a beta damnit! Stats don't even carry over. So... 12 year olds for the win (because of my unfair advantages, and also for having played the beta before most of them, hehe)!
Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...
