Zombie Towers: Merge TD Defense

Zombie Towers: Merge TD Defense flips the classic tower defense formula by putting fusion at the heart of your strategy. Instead of simply building new units, you'll drop identical turrets onto the grid and watch them merge into more potent versions, unlocking new firing patterns and devastating perks. This clever twist means every placement decision matters — you're not just positioning firepower, you're crafting an ever-evolving arsenal. As the zombie tide swells, you'll need to balance quick placements with long-term planning. Rushing to merge too early can leave gaps in your line, while hoarding basic towers risks being overrun. With a variety of enemy types and shifting terrain, each wave forces you to adapt. It's a satisfying loop of merge, upgrade, and defend that keeps your mind sharp and your reflexes ready.
