What is Merge Tower Defense?
Merge Tower Defense is a popular Roblox strategy game that puts a unique twist on the classic tower defense genre. Instead of simply buying upgrades with cash, players must place units on a grid and merge two identical towers to create a more powerful, higher-level version.
As waves of enemies become increasingly difficult, players must manage their limited space, strategically place their units, and balance their resources to build an impenetrable wall of fire. With various maps, diverse tower types, and challenging boss fights, the game requires both quick thinking and long-term planning.
