Combat is...eh....whats the best way to word this.......lacking.
Considering you shoot stuff for 70%+ of the game from what I could tell combat should be very polished and fleshed out but its not. You cant run out of ammo like...ever, if you do congrats you just won the game and the weapons are so bland, the same kind of boring crap we see in every game, a step back from bioshock 2.
Unless you hoover up ammo from vending machines every fight you can quite easily run out of ammo...
I do agree that the weapon selection is rather tame though. 2 hand guns, 2 shotguns, 2 mid range rifles, 1 semi auto rifle and 1 sniper rifle and 2 grenade launchers. Nothing quite like the Rivet Gun or the Harpoon.
I think its major step back there was the removal of ammo types which really did suck. No Anti-Personnel machine gun rounds? No armour piercing or high explosive rockets?
