A 5v5 competitive PvP mech shooter from Plarium. Build battle mechs, equip dozens of weapons, and drop into short matches against players around the world.
What is Mech Arena
Mech Arena is a competitive multiplayer mech shooter from Plarium Global Ltd. Matches are short, five-versus-five fights on compact arenas where players pilot custom mechs, swap weapons mid-fight, and chase objective control. The game launched in 2021 and has crossed 50 million installs on Google Play with an active ranked ladder and weekly events.
The build-and-battle loop sits at the center. You pick a mech chassis from a roster of more than thirty, mount up to four weapons across the slots, tune armor and shields, and take that loadout into a match. Some chassis prioritize mobility, others stack health for brawling, and a few specialize in burst damage from cover. The roster keeps growing as new releases drop seasonally.
The standard build is free with optional purchases for A-Coins, the premium currency that buys faster progression on mechs, weapons, and cosmetic skins. The Mod APK on this page swaps that gated economy for an unrestricted one so the build phase is the focus, not the wait.

What this mod offers
The modified Mech Arena 3.430.00 build unlocks the time-gated progression and the premium currency that normally fund A-Coins purchases. The combat is identical; the difference is what you walk into a match with.
- Unlimited A-Coins and Credits.
Premium currency reads as effectively limitless inside the hangar. Buy chassis, weapons, and skins without the usual cooldowns or top-up screens.
- Mod menu toggle.
An in-game overlay exposes the mod options. Toggle features on and off per match instead of committing to a single profile.
- Unlimited ammo.
Every weapon fires without depleting its magazine. Cooldown timers between shots still apply, so the game balance does not become trivial.
- All mechs and weapons unlocked.
The full roster shows up as already-owned in the hangar. Test loadouts you would normally need weeks of progression to assemble.
- No ad interruptions.
The video ads that normally precede daily rewards and event tickets are removed.
- Speed and reload modifiers.
Optional toggles for movement speed multiplier and instant reload. Leave these off in ranked matches to avoid suspicious patterns.

- 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.

- 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.
