Merge Turrets: Tower Defense

Place turrets along the enemy route and merge two of the same type and level to upgrade them. Combine different weapons and adjust your layout as enemy waves advance in this merge tower defense game.

Merge and position your turrets
Board space is limited. Merging strengthens a turret and frees a tile, but leaves you with one fewer gun on the field. Decide when to merge and when to keep more turrets covering the route. You can also move turrets during battle to adjust their coverage.

Choose your weapons
Rapid-fire guns, artillery, flamethrowers, lasers, and missiles fill different roles. Use their range, attack speed, and firing patterns to combine focused fire with area damage. Place mines on the road for extra damage where you need it.

Upgrade between battles
Collect coins and weapon shards to improve your weapons. During combat, choose damage, attack speed, or range bonuses to suit your current lineup. As tougher enemies and bosses arrive, keep your weapons upgraded and your turrets in position to cover the route.
