Fortress Merge
About Fortress Merge
Fortress Merge is an action-packed puzzle defense game where merging, upgrading, and strategic placement decide whether your castle stands or falls to relentless zombie tribes. Construct defensive structures and forges, choose upgrades and boosters, and build the most solid line of defense against the undead.
How to Play Fortress Merge
Fierce zombie tribes are attacking the kingdom, and every wave must be repelled before they reach the palace. Place defensive buildings and unit forges on the battlefield, merge and upgrade your army, then earn extra points as each wave falls. If the zombies breach the palace and the health bar drops to zero, the level is lost. Survive all attack waves with the castle intact and victory is yours.
Bosses
After completing every 5 levels, a Boss encounter awaits — requiring even greater diligence to defend the castle.
Difficulty Progression
As the levels advance, landscapes change and demand adapted defensive structures, while zombies grow increasingly bloodthirsty, better armed, and more resilient.
