Game needs to be re-made. They clearly didn't put as much effort into this as they did the later games.
I'm sure if this was remade, perhaps with, I don't know, guns that sound different, or upgrades, it would be on the front page real fast.
Why are pistols stronger than assault rifles? The literal translation of an assault rifle is "an automatic gun with a cartridge that can carry bullets stronger than a pistol but weaker than a rifle."
