Rancor

"Not surprisingly, the founders of Rancor aren't terribly nice people. Their slogan is "Hold hate in your hands". Rancor is a boutique weapons and ammunition manufacturer that go out of their way to contravene every war crimes convention, protocol and idea of humane killing. Their weapons are designed to burn, chemically disrupt and shred flesh and they make no apologies for it." - official description -

Rancor is a manufacturer in SAS: Zombie Assault 4. It makes very unique and, when used effectively, powerful weapons like Hard Thorn and Stripper. It is the only industry to make chemical weapons: the Poison Claw and Stripper. Besides the Hard Thorn, Poison Claw, and Stripper, there are the Mixmaster, which is an energy-damaging Assault Rifle with superior fire rate and the ability to shoot two bolts at a time, the Rancor Shredder, which fires bladed disks that bounce off of walls, the Rancor Hotspot, which shoots lasers to rip apart anything, and the Heartburn, which fires molten bullets to burn stuff.

The overall design for Rancor guns is a red base with a skull and either chainsaws or blades on the bottom. The Stripper and Poison Claw are very good weapons late game in their  [RED]  versions, while the Hard Thorn is adept at clearing trash mobs. The Mixmaster, however, is not as good as the others, as it is rare, and is outclassed by other weapons for its late level in which it is unlocked. The  [RED]  versions of Rancor weapons will have the white skull lit up bright red and also have bright red dots on the gun as well.
