A 5v5 competitive PvP mech shooter from Plarium. You build battle mechs, bolt on a stack of weapons, and drop into quick matches against players around the world.
What is Mech Arena
Mech Arena is a competitive multiplayer mech shooter made by Plarium Global Ltd. Matches are short. Five players a side, compact arenas, custom mechs you can re-gear mid-fight while you fight for objective control. It launched in 2021 and has passed 50 million installs on Google Play, with a ranked ladder and weekly events that keep regulars coming back.
The build-and-battle loop is the heart of it. You pick a mech chassis from a roster of more than thirty, mount up to four weapons across the slots, set your armor and shields, then take that loadout into a match. Some chassis lean on speed. Others pile on health for brawling, and a handful are built for burst damage from cover. New mechs keep arriving each season, so the roster never sits still.
The standard game is free, with optional purchases for A-Coins, the premium currency that speeds up progress on mechs, weapons, and cosmetic skins. The Mod APK on this page trades that gated economy for an open one, so building is the point and the waiting goes away.

What this mod offers
The modified Mech Arena 3.430.00 build opens up the time-gated progression and the premium currency that usually bankrolls A-Coins purchases. The combat itself is the same. What changes is what you bring into the match.
- Unlimited A-Coins and Credits.
Premium currency behaves as if it never runs out inside the hangar. Grab chassis, weapons, and skins without the usual cooldowns or top-up screens.
- Mod menu toggle.
An in-game overlay puts the mod options in front of you. Flip features on or off per match instead of locking into one profile.
- Unlimited ammo.
Every weapon fires without draining its magazine. The cooldown between shots still ticks, so matches do not turn into a walkover.
- All mechs and weapons unlocked.
The full roster shows up already owned in the hangar. Try out loadouts that would normally take weeks of grinding to put together.
- No ad interruptions.
The video ads that usually run before daily rewards and event tickets are gone.
- Speed and reload modifiers.
Optional toggles cover a movement speed multiplier and instant reload. Leave them off in ranked matches so your play does not look suspicious.

FAQ
- Is Mech Arena free to play?
- Yes. The official Mech Arena app on Google Play is free with optional in-app purchases for A-Coins. The mod build on this page removes those paywalls but is unofficial.
- Will I get banned for using the mod?
- The mod bypasses the in-game economy, which the Plarium anti-cheat detects. Use a guest account on a separate Plarium login and avoid ranked play to reduce the risk to your main profile.
- What is the difference between the official version and the mod?
- The official version requires earning or buying A-Coins for progression. The mod unlocks the premium currency and the full mech roster up-front, plus optional reload and movement modifiers.
- Does the mod work offline?
- No. Mech Arena is online-only because every match runs on Plarium servers. The mod removes paywall friction but cannot make matches playable offline.
- How big is the download?
- The Mech Arena 3.430.00 APK is around 240.4 MB. The first launch downloads an additional resource pack of approximately 240.4 MB, so reserve 1 GB of free space before installing.
