Merge Guns

About Merge Guns

Merge Guns combines strategic merging and tower defense as you place and combine weapons on a grid to strengthen your firepower. Buy guns using gold, then merge identical models to upgrade their capabilities and fend off waves of advancing alien enemies. As new weapons unlock and tougher foes appear, you'll need to carefully plan your layout to hold the line. The game features multiple weapon tiers, boss encounters, and persistent upgrades that carry over between attempts, adding variety and challenge to each defense. With automatic firing and options like airstrikes for heavy waves, Merge Guns offers a thoughtful mix of strategy and action gameplay.

Stop enemies crossing the line, use Airstrike against heavy waves, and spend earned cores and Salvage on permanent upgrades between runs.
