Boo Brigade

About Boo Brigade: Spooky Merge Tower Defense

Boo Brigade is a spooky merge tower defense where torch-carrying villagers assault a candy castle every night, and your monsters stand as the only defense between them and the pumpkin gate. Summon creatures onto the board, merge identical ones into stronger ranks, and hold the line across endless nights. The pressure never fully lifts — each wave pushes harder, and the goal is simply to last as long as possible.

How to Play Boo Brigade

Each summon places a random unit on a free tile beside the road. The cost in souls rises slightly with every summon, so managing the board matters. Drag one unit onto a matching unit to merge them into a higher level; merging goes up to level 5. Units attack on their own once placed, and tapping any unit shows its stats or lets you sell it when the board fills up.

Two spells help when the road gets crowded: Moonstrike delivers a heavy hit, and Frostbite slows an incoming wave. Calling the next wave before it arrives automatically pays bonus souls — a worthwhile risk when the board is in good shape. Souls banked over time can be spent on permanent upgrades.
