Beware, the game suffers from extremely bad screen tearing regardless of where you play it. I'm sure it wasn't this bad in previous Far Crys. I just wish there was like an upgrade system. Perks seem to be on clothes that you find and wear. Plus you can get a sniper rifle pretty early on. Once you've added a silencer, you can go the whole game really, without ever needing to find a new weapon.
I didn't like 5 at all - mainly because of the religious stuff.
