What is Mech Assemble: Zombie Swarm?
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.

Why Aren't My Mech Assemble: Zombie Swarm Codes Working?
Mech Assemble: Zombie Swarm codes can stop working at any time. Here are the most common reasons a code might fail and how to fix each one:
- 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 — copying 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 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.
