Summon them. Merge them. Defend the wall!
Merge Cats Defender is the purr-fect blend of merge puzzle and tower defense (TD) strategy. Summon brave gun-slinging cat heroes, merge two of a kind to forge stronger warriors, and deploy them across 5 lanes to hold back the endless zombie horde. Easy to learn, tough to master - can your cats survive the apocalypse?
SIMPLE TO PLAY, HARD TO PUT DOWN
Tap to summon a cat, drag two matching cats together to merge, and place your heroes on the front line. One-handed, quick-session gameplay that fits any coffee break.
MERGE AND UPGRADE 15 CAT HEROES
Combine cats to climb through 15 unique tiers - each merge makes them faster and hit harder. Permanently upgrade damage and fire rate between battles to build the ultimate defense squad.
DEFEND 5 LANES vs THE ZOMBIE HORDE
Waves of zombies pour down five lanes toward your wall. Position your cats wisely, focus fire, and don't let a single one break through.
TRAPS AND POWER-UPS
Unlock game-changing add-ons - drop TNT to blow up a whole lane, lay spike traps, double your coins, or trigger a rapid-fire frenzy. Unleash them right when the horde swarms.
40 LEVELS PLUS EPIC BOSS BATTLES
Fight through 40 hand-crafted stages across escalating chapters, with a towering boss at the end of every run. Tougher enemies, bigger rewards.
