I picked the game up at my local target for 25 on clearance. Wasn't honestly expecting a whole lot and prayed it was less rpg-ish then stalker as I do love me a good post-nuclear fallout story!
Anyway beat the game tonight on normal and I must say this is a game that really did challenge me and caused me to reload form checkpoints more often then any other FPS I can remember. Ammo doe sseem to run out quickly but TBH, if you actually go back and look around at some points after you've cleared it, you'll end up with thousands of rounds I overlooked.
I figured that it usually takes me 5-10 hours to read a good 300-400 page book and I finished the game in that amount of time. 26 bucks for this game was a very good investment as I enjoyed the game thoroughly and even thought the story was very well done.
I highly recommend this game!
