Constant

A Serial Killer
Well it's rather clear how Constant gained his nickname, especially after his constant spree of murders. Course, he's not a good guy, but sometimes you have to do what's write in spite of such. Ash was apprehended by Hazard and spent time in a supermax prison, escaping shortly before the world ended, and ending up here, forced to side with good, because even the bad guys are out of Constant's League.

Multiplayer
A high powered shotgun isn't often his weapon of choice, but he likes how it kills. Each time Ash gets a kill he speeds up by a small percent, this can make his character faster than Hazard in some cases, but it makes him jump lower.

What a Rush
If Ash is close to execution, but the opponent fails, he will gain 15 seconds of invulnerability and he kills in one shot.
