Mech Assemble: Zombie Swarm codes (December 2025)

Updated: December 9, 2025

We added a new code!

What chance do zombies stand against mechs? None, if you make your loadout as powerful as it can be, and that’s where Mech Assemble: Zombie Swarm codes come in! Sure, the zombie waves get tougher and tougher, but nothing can beat your mechanical menace.

With Mech Assemble: Zombie Swarm codes, you’ll get Diamonds, Gold, Mech Shards, and Part Chest Keys. In other words, much of what you need to upgrade your mechs into the killing machines they were meant to be! At that point, you’ll be able to choose whether you want to engage in PvE or PvP and where to dominate the battleground. And if you can’t get enough of colossal mechanical constructs that wreak havoc on your enemies, you’ll want to check out Mech Arena promo codes, too!
