Mech Arena hands out free A-Coins, Credits, crates, and even rank 3 mechs through promo codes that Plarium releases periodically. Redeeming them takes a couple of minutes and gives your hangar a head start without spending real money.
Working Mech Arena codes
You can only redeem one code per day, so it’s worth prioritizing the ones locked to new or returning players before they expire.

Codes tied to new or returning players only work within the first 72 hours after you create your account, so redeem those before any general codes.
How to redeem codes in Mech Arena
Codes are entered through Plarium’s web portal rather than inside the app itself, so you’ll need your Player ID handy before you start.
A successful redemption sends your rewards straight to your in-game inbox, or adds them to your inventory automatically the next time you load into Mech Arena.
Expired Mech Arena codes
These codes no longer return rewards when entered on the redemption portal.

Where new codes get announced
Plarium typically posts fresh codes around updates and seasonal events through the game’s own channels rather than a single dedicated page. Checking the Mech Arena X account or the Mech Arena forum is the quickest way to catch a code before it expires.
Since only one redemption is allowed every 24 hours, work through the new-player codes first if your account is still within its first 72 hours, then move on to the general codes while they remain active.
