Merge Mech
Merge. Transform. Demolish. Drag two junk cars together and watch them slam into something bigger — a tuned racer, a walking robot, an armored mech, and finally a seven-story TITAN. Then send your three strongest out to auto-battle and clear 100 stages across 10 worlds.
Merge. Transform. Demolish.
Your garage is full of junk cars. Drag two identical ones together and watch them slam into something bigger — a tuned racer, a walking robot, an armored mech, and finally a seven-story TITAN. One-tap AUTO MERGE clears every matching pair and sorts the board by power; sell what you do not need and deploy exactly who you want.
No timers on your fun. No twitchy controls. Pick your three fighters and the fight plays out on its own — Double Hit, Heavy Armor, Shoulder Cannon, Regen, Critical stacking as they level. Just the satisfying crunch of a merge and the payoff of watching your squad flatten a boss.
Four families, seven levels each
Tank
Counters. Highest HP and Defense, and it hits back at whatever swings first.
Truck
Adds HP. Built tough enough to keep the squad standing deep into the boss round.
Racer
Evades. Strikes first and slips the hits it cannot afford to block.
Sedan
Hits twice. No weak stat, and every attack lands a second time.What you actually do

Frequently asked questions
What is Merge Mech?
Merge Mech is a free merge and auto-battle RPG by HercGames. You merge two identical units to create a stronger one, evolve them from L1 vehicles up to L7 Titans, then send a three-mech squad into automatic battles across ten worlds.
How does merging work?
Drag one unit onto another of the same type and level. They fuse into the next level up — an L1 Tank plus an L1 Tank becomes an L2 Tank, and so on to L7. Each step changes the model and raises Attack, HP, Defense and Speed.
What are the four vehicle families?
Family perks decide fights: Sedans hit twice, Trucks add HP, Racers evade, Tanks counter. Each family runs 7 levels from scrap car to TITAN, and a good squad mixes them rather than stacking one family.
Do I have to control the battles?
No. Pick your three fighters and the battle plays out round by round on its own — no timers, no twitchy controls. Your decisions happen in the Garage, not mid-fight.
What happens after stage 100?
The CHALLENGE TIER opens — the same world map with enemies a hundred times stronger and your whole garage carried over. Switch between Normal and Challenge any time; progress is tracked separately.
Does it work offline?
Yes. Merge Mech plays offline in portrait with one thumb, auto-saves, and needs no account. Sound and haptics can be switched off, and the garage keeps earning coins while you are away.
Where can I download Merge Mech?
Merge Mech is free on Google Play for Android and on the App Store for iPhone and iPad, with optional in-app purchases.
