Fortress Merge

About Fortress Merge

Fortress Merge is an action-packed puzzle defense game where merging, upgrading, and holding your castle against endless enemy waves drives every decision. Built for fans of zombie tower defense, roguelike challenges, and strategic castle games, it blends grid-based base building with wave combat into one addictive strategy experience.

How to Play Fortress Merge

Place and merge military buildings on your castle's grid to build a defense formation, then trigger combat to watch your warriors engage incoming enemy waves automatically. Survival depends on how well you merge and position your forces before each fight.
