I actually have a review for it in the game reviews thread, so you can read what I think about it there!
Anyways, still playing Metro 2033. I had to sell a bunch of Ammo to get the best assault rifle, and armor in the game, so pretty much all my guns have little ammo, aside from my Assault Rifle.
EDIT: Still playing Metro 2033. Librarians are assholes! I barely have any ammo!
I read your review, sounds awesome but also sounds short. I'll probably rent it. Thanks.
