FireLine: Merge Defense

FireLine: Merge Defense is a tower-style defense game where you merge cannons to grow stronger. You hold a tactical position and fight waves of cubes plus powerful bosses.

Use the mouse to aim, place, and merge your guns on the field. Combine matching cannons to upgrade them before the next wave arrives.

Survive increasingly tough enemy waves and stop bosses from breaking through your line. Unlock and upgrade a wide arsenal so your merged cannons can handle later stages.

Merging turns weaker guns into stronger versions with better firepower. Smart combinations let you defend longer without running out of space on the battlefield.

Yes. Cube waves and boss fights grow more intense as you progress, so upgrading your cannon lineup through merges becomes essential to keep your defense alive.
