The MARK III Assault Rifle is a weapon found in System Shock.


This full-sized combat rifle in use in the 2070's is based on the 2064 Interlocutor KR-5.

While the MARK III packs an incredible punch (especially with Penetrator rounds) it suffers from sadly undersized magazines, with less rounds apiece than the clips in all three of the sidearms found aboard Citadel Station. Relying on the MARK III as a general-purpose weapon is thus inadvisable, but it does make an excellent tool for picking off the tougher Cyborgs and Robots.

Ammunition Types

MagTip Icon MagnesiumTips Magnesium Tips (10) - Caseless, caustic slug that maximizes wound damage.
Penetrators Icon Penetrators Penetrators (8) - High-power rounds that can penetrate 20mm steel armor.

  • Modern assault rifles hold anywhere from 20 to 40 rounds in their magazines and are actually a type of automatic rifle, making the MARK III's low magazine capacity and semi-auto nature a curious design choice: it's technically a carbine.
