YMMV / Nightmare of Decay

• Game-Breaker: The Submachine Gun is this in Dungeon Escape, one of the game's unlockable extra modes. How the Submachine Gun is meant to work is that it's a high ammo weapon that in exchange does low damage per shot. All well and good, until you realize that each bullet does around the same damage as the Pistol. The result is that, when combined with the relatively low credit cost of its ammo and the fact that you'll constantly be finding ammo for it if it's the only weapon you buy between floors, the Submachine Gun goes from a solid weapon to a straight upgrade to the pistol that can be used to kill enemies from all ranges via tap-firing or short controlled bursts, making the Dungeon Escape mode much, much easier.
