What is Merge Tower Defense?
Merge Tower Defense is an addictive Roblox strategy game that combines the classic tower defense genre with “merge” mechanics. Instead of simply placing towers and watching them shoot, players must strategically place units on the map and merge two identical towers to create a single, much more powerful version.
As waves of enemies become stronger and faster, players must manage their resources—Diamonds and Gems—to buy new units and upgrade their defensive line. The game features various maps, unique tower types, and challenging bosses that require a mix of quick thinking and long-term planning to defeat.
