I've recently been playing the survival mode of pixel gun, and realized that sometimes with my "Golden Mega Destroyer" and I realized that someitmes the gun One-hit's monsters that usually take two hits (Like the zombies and skeletons on the first two waves) also sometimes my secondary can kill flying enemies in one hit but other times it takes two, what is this? Is there some critical that I don't know about?
