―Official Description
The Z-5 Heavy (sometimes shortened as Z-5) is an LMG featured in SAS: Zombie Assault 4 (both PC & mobile) as a starting primary gun exclusively for the Heavy class.


As a starting gun, Z-5 Heavy comes with decent damage, high capacity & 2 pierce, which is recommended for rookie players who prefer defense playstyle. However, Z-5 will become ineffective for later levels as it suffers poor stats when compared to other LMGs. Also, It can't be augmented without EACs.

You should sell this gun not for money but a slot or simply replace it with a better gun that is randomly found in Strongboxes. Though Z-5 Heavy can be augmented with EACs, It's recommended not to do so due to EACs' rarity.


Z-5 Heavy is based on Stone LMG 96. Its ammo box is appeared to be fed from the right side, mirrored to most real-life LMGs. However, this makes Z-5 look like another real-life MG called Stoner LMG 86. It has the word "Z-5" on its cover latch. It has scratches & some duct tape wrapped over its stock and foregrip, which means this gun is under bad condition but still usable.


  • Its real-life counterpart ironically only weighs 10 pounds (4.54 kg) in real life.
  • The Z-5 is the only Z-Arm Tech weapon whose real-life counterpart is not in SAS 3. More image can be seen here.
  • Many people believe that this is the best of the 3 starting weapons, even better than the RIA 7. It's in no way a great weapon, but at the starting ranks, it's not too bad.
  • As a starter weapon, it does not have a RED or Selection 004 version.
  • For some reason, an image of the Selection 004 Z-5 Heavy exists in the files of the mobile version of SAS 4.
  • Like the other starter equipment, this gun cannot be crafted.
