Mech Assemble: Zombie Swarm codes not working?

If you're having trouble claiming rewards, check these common issues related to Mech Assemble: Zombie Swarm codes:

  • The code has expired. Many codes have a short shelf life, sometimes lasting only a day or two. If you’re seeing an error, the code may have already been deactivated. Check the status tag next to each code on our list.
  • Double-check for typos. Capitalization doesn’t matter for these codes, but spelling does. Even one wrong letter or number will cause the code to fail, so copying "MGFEB777" from our list is the safest option.
  • Already redeemed. Codes are single-use. If you’ve redeemed a code before, even months ago, it’s permanently claimed on your account and can’t be used a second time.
  • Platform or region mismatch. With versions on iOS, Android, not every code works across all platforms. Double-check that the code applies to the version you’re playing.
  • Check your in-game mail. In Mech Assemble: Zombie Swarm, rewards from codes like "MGFEB777" are often sent to your in-game mailbox rather than appearing on screen. Check your mail, gift box, or inbox after redeeming to collect your items.

About the Game

Mech Assemble: Zombie Swarm is a roguelike action survival game published by ONEMT. In a post-apocalyptic world, players act as engineers who must construct their own custom battle mechs to fight off endless waves of mutant zombies. The game stands out for its "Modular Assembly" system, allowing you to mix and match over 100 different parts (heads, arms, legs, weapons) to create unique robots—ranging from Gundam-inspired warriors to chainsaw-wielding tanks. It combines the bullet-hell intensity of Survivor.io with the customization of a mech builder.

What's the most valuable code in Mech Assemble: Zombie Swarm?

For new players, we recommend starting with the code "THX40000". This code is reported to have the highest success rate by our users.

What is the "Level 25 Wall"?

Many players report a significant difficulty spike around Chapter 25. To pass this without spending money, you must switch from "AoE" (Area of Effect) weapons to "Single Target DPS" weapons (like the Laser Cannon or Drill Arm) to melt the Elite Bosses before they overwhelm you. Grinding previous stages for "Blue Cores" to upgrade your weapon parts is essential here.

What is "Green Energy" used for?

Green Energy (the green cubes dropped by zombies) is the in-battle currency. It resets after every match. You use it to select one of three random upgrades (Roguelike perks) each time you level up during a run. Prioritize Fire Rate and Multishot upgrades early in a run to handle the swarm density.
