The gun isn't broken. The power of the weapon overcompensates for the range. The bullet actually goes above whatever you're aiming at. Aim below your target
This game is very cracked. One, if 99,99953 percent of the population died, that would mean the population died 99,999 times. Secondly, "Survived animals mutated"? what the hell is that supposed to mean? Thirdly, the only use for jumping would be to avoid small animals, so how in the hell are they still hitting me? and lastly, what kind of idiot would put the handgun in the shop? and if that's in the shop, what the hell am I using in the beginning?
People say this game sucks often, but it's because it was intended for a younger audience. The "I'll be watching you too" part gives THAT away. plus the fact that there's no gore, cursing or even use of weapons
