I dont know dude, I was just playing Resistance today and I have to say, this game is unforgiving in terms of a challenge. How far are you into the storyline? I just made it to "Devil at the Door". Those bizarre "ANGEL" creatures are a pain in the butt.
Everyone has said so many bad things about Resistance, but I have to say, I like this game...
My co-workers say "It's the most generic FPS..." I don't know, I've never really seen weapons, generades, and such like in these. I do admit it does tend to rip off Halo once in a while, but the storyline is weird. The entire "Aliens taking over and turning humans into Chimera" is pretty cool.
Yet I would have to say, if you give it more time, then it tends to grow on you a bit.
