The M.S.C.M. (Mek Siege Cannon Module) is an item introduced in Extinction and also available on Genesis: Part 2, Lost Island and Fjordur.


Pressing C, Right Stick, Right Stick, Right Stick will make the  Mek enter its turret mode by bending over while using its sword as a stake. In this position, the cannon can be aimed and fired after a brief warm up period while holding Lmb, RT, R2, RB. Upon firing, there is another short cooldown period before the cycle is completed.

Requires  Cannon Shell to fire.


  • Each time the M.S.C.M. is unequipped, this will lose 1200 durability until becoming broken.
  • While on turret mode, the Mek cannot move and takes 2x damage. This module also provides no passive armor, so caution is advised when using it.
  • Higher quality cannon modules do not affect the damage of the cannon shell.
  • One of the easiest ways to tame a  Titanosaur, dealing 4800 torpor if aimed to the head. Extinction does not contain any Titanosaurs, but the Mek and M.S.C.M. can be uploaded, then downloaded at other maps that have Titanosaur.
