The SCMITR Bio-shotgun is a semi-automatic shotgun in SAS: Zombie Assault 3 and is one of the most powerful, if not the most powerful, guns in the game. It costs 60 NK coins, or $5.99 on the mobile version. The power association is due to the fact that after shooting a zombie, the zombie takes damage over time, and the corpse explodes (with damage significantly higher than the MGL-140), damaging nearby zombies. Thus, it is best used in close quarters and/or on tightly-packed zombie groups. At near point-blank range, the gun is also able to kill Butchers and Mamushkas in one shot, making this a truly devastating weapon to wield. Although its ammunition is expensive (at $500 for 100 rounds), usage of ammo is very slow, and the pros outweigh the cons. The AA-12 shotgun, in comparison to the SCMITR, is less damaging for its rounds and do not cause a corpse to explode.

It has more damage than the Mark II per shot so the damage bar is highly inaccurate. The 8 round capacity is also inaccurate; it is able to carry 12 rounds (24 with the "High Capacity Magazines" skill).


  • In the SCMITR purchase screen, the description says that it uses BioTox in its ammunition. This is somewhat confusing, as BioTox is a biological weapon and is responsible for causing the zombie apocalypse in Zombie Assault 3.
  • Even though the intention was that this gun could only be purchased and used when the player reaches Rank 47, it is possible to buy and use this gun at Rank 1, and have an unfair advantage in the early game, provided the player is able to buy sufficient ammo.
