About Merge Legion

Merge Legion combines merge mechanics with lane defence. Identical units combine into stronger ones, and the board space you free up decides whether you can afford the next wave's counter-unit.

Each of the forty campaign stages introduces one enemy type that beats a specific composition, so a build that carried you through stage twelve will fold on stage thirteen unless you adapt.

How to play

  1. 1Merge early and often — two low-tier units on the board are worth less than one tier above.
  2. 2Keep two free tiles at all times so a needed counter can be summoned mid-wave.
  3. 3Check the wave preview before spending gold; the icon shows the incoming enemy type.
  4. 4Upgrade the gate only when a wave has already broken through once; unit tiers scale better.
