Merge Gun Idle: Monster Defense is an arcade merge-defense game where you buy weapons, merge identical guns into stronger ones, and automatically fight off waves of monsters. The further you go, the tougher the enemies become, so you need to build an efficient weapon grid, upgrade your stats, and strengthen your defense between waves.
The game features a weapon merge system, upgrade shop, bosses, multiple enemy types, manual target selection, ad-based revive, and steadily increasing difficulty. Your goal is to build the strongest arsenal possible and survive as long as you can.
How to play
- Tap `BUY` on an empty slot to purchase a new weapon.
- Drag identical guns onto each other to merge them into a stronger one.
- Weapons fire automatically at enemies within range.
- Between waves, upgrade damage, fire rate, reward, and health in the shop.
- Tap `START WAVE` if you want to begin the next wave early.
- Do not let monsters reach your base.
