About Merge Defense
Build an unstoppable arsenal by merging guns, defend against endless waves of enemies and bosses, collect power chips, and climb the ranks for lasting bonuses in Merge Defense!
How to play
YOUR TASK: combine weapons to expand your arsenal and withstand increasingly powerful attacks. PROTECTION: foes keep coming, and your guns shoot automatically, earning cores both online and offline. COMBINATION: select one gun and then another. If they're the same level, they merge and upgrade; if one is empty, it moves; if they're different, they swap. ATTACK WAVE: press play to bring on the next tough wave. Clear it to get a large bonus. Every fifth wave features a boss. If you fail a wave, your arsenal remains intact — just try again. CHIPS: enemies leave behind chips. These chips can also be merged (if they're the same type and level) and enhance your entire arsenal when equipped. ENHANCEMENT: use cores to permanently improve your game with things like auto-merger, forge, larger board, critical hits, and more. Ascend to reset your guns and get permanent star bonuses.
