Merge Defense: Army Behind the Wall

Merge Defense: Army Behind the Wall is a strategy game where you defend your fortress against endless waves of monsters in this addictive merge tower defense game. Recruit powerful warriors, combine identical units to create stronger defenders, and build an unstoppable army before the next attack begins.

Archers excel at taking down single targets, while mages unleash powerful attacks that damage multiple enemies at once. Position your units strategically, then start the wave and watch your army fight automatically as you earn gold from every defeated monster.

Travel through unique worlds, including swamps, frozen lands, deserts, and mysterious mushroom forests. Each region ends with a powerful boss that will put your strategy to the test. As you progress, your army and collected gold stay with you, allowing you to grow stronger with every victory.

Upgrade your warriors, unlock powerful magic, reinforce your wall, and prepare for increasingly difficult battles. Build the ultimate defense and stop the monsters from breaking through.

How to Play

Buy warriors with gold — they stand behind your wall.

Merge two identical warriors into one stronger warrior. That's the only way your army gets stronger.

Place archers and mages: archers hit one enemy, mages hit several at once.

Press Start — your army shoots on its own and earns gold for enemies.

Survive the wave, then buy and merge more warriors.

A boss appears at the end of each world. Beat it and move on — your army and gold stay with you.

Don't let enemies break the wall. If it falls — you lose!
