Legion TD is a team-based tower defense (TD) game mode originating from Warcraft III custom maps and later reimagined as standalone titles (e.g., Legion TD 2). Players build waves of defensive units (legions) to stop enemy waves, while also producing units that attack other players. Success requires economy management, unit synergies, positioning, and adapting to opponents’ strategies.

A great Legion TD guide always returns to this balance: It’s okay to leak a little early if it builds a massive worker lead.

You use "Lumber" (or Mythium) to train workers. These workers generate the resources needed to send mercenaries to your opponents, which in turn increases your permanent gold income.
