SWIPE/HOLD: Merge Defense

The battle never pauses

Enemies advance across four lanes while your towers and equipped weapons fire automatically. Your one direct command changes everything: swipe the 4x4 board to move and merge every tower at once.

Merge for impact

Matching towers combine into a stronger rank. Every successful merge launches an immediate power shot, so a smart swipe can turn a collapsing defense into a comeback.

Build a run

Choose up to two weapons and three relics. Railguns punch through armor, Tesla arcs clear groups, missiles burst across lanes, and freeze buys time. Match weapons with their relics to evolve them into run-defining attacks.

Read the next wave

Swarms, rushers, armored enemies, and bosses do not fall to the same answer. Watch the wave forecast, strengthen the right part of your build, and decide when to chase one more merge.

Endless by design

Every run keeps escalating. Push your best wave, learn the enemy traits, and find combinations that feel completely different from the run before.
