Reading through this thread I find it crazy how many of you guys are (seemingly) playing on Uber difficulty. How are you playing the game exactly? Super slow and steady? I've been playing through the entire game on the default middle difficulty, and I've found it quite challenging at times. Enemies take you down fast if you're out of cover, and given that you occasionally have to scrounge for ammo (love the game, but if I had one complaint, it's that you don't get enough ammo) it's possible to find yourself in some really bad situations from time to time.
I'm actually about halfway through
and I just knocked the difficulty down a notch as I found the game becoming a little too crushing for my liking. So yea, if you're playing on uber, what's your play style?
