Yeah, the ammo was an issue for me too. I don't think they put the ammo crates in proper areas. I ended up going through all my assault rifle, pistol ammo and resorted to my blade to hack and slash until I found a crate.This was not on my radar but after reading a few things yesterday I figured why not, I had a $5 credit from Microsoft Rewards so only cost me $35. If this was a $60 game I would of waited for a sale but this seems like a solid budget game from the little I was able to play last night. The 2nd NY level did glitch on us at the train and would not let us move forward, I had to eventually quit and received zero XP which was frustrating.
Definitely not as good as Left For Dead IMO, not sure I will enjoy the levels as much, it needs more enemy variety and I found myself needing to constantly find ammo and ran out quick but for what it is I can seem myself putting some time in especially with the leveling up system. I hope any glitches and bugs get worked out and they support the game.
