Slayer

The Slayer is one of the many Chaos creatures. The monster resembles a Fiend, albeit larger and more heavily armored, not to mention the greatly extended arm bones resembling bat wings. It can buff itself and all surrounding Chaos expect Skull Fish, restoring up to 50 points of health, although this can not exceed the enemy's maximum health value. The Slayer has two attacks, predictable by which arm it uses. The left arm will shoot a vertical wall of fire while the right arm will shoot a horizontal wall of fire. Both attacks have slight homing properties.

The Slayer is first seen in the Intro, where two of them are standing next to a Hunter. It is first fought at the end of Genesis Part 2, and at least one appears per map starting in The Forge. In both cases, it is fought in close quarters with Chaos enemies nearby. The best means of combating the Slayer is to use high-damaging weapons such as the Super Shotgun or the Grenade Launcher. Rapid fire can also work in a pinch although do be aware that the Slayer is immune to headshots.
