Creature X

Creature X is a half-human, half-alien creature created by the forces of The Sphere for combat purposes. It appears in Prey.

Overview
Creature X is made out of two creatures: the first one is a human being with cannons that replaced his arms, the second one is a reptile-like creature who is very agile. It doesn't have back legs, instead it appears to have either trailing intestines or some kind of metal cables. Humans that were fused with this creature have no control over it.
