A terrorist who places little value on the lives of those who would interfere with his plans. He is the prime suspect in a number of violent events in Mars. He is encountered in the mission Escort Train.
Catastrophe is a middleweight four-legged AC equipped with anti missile extensions, a chain gun, a small rocket launcher, grenade launcher weapon arms and an overboost core. The unit is capable of ignoring weight restrictions.
In order to survive his attacks, you need to avoid his grenade launcher arms. As long as you can avoid this you'll do fine. He can't fly with the chaingun but with the quads he can still move quickly. He isn't too much of a threat.
