Ancient Arbiter

Auto-battler tower defense

Ancient Arbiter is a PC auto-battler built around a tower defense structure. You rebuild an Arbiter tower in the ruins of Aurveil, recruit wasteland survivors and salvaged tech, and prepare to hold off waves of enemies. There’s no tower placement or real-time input during combat: you draft heroes, arrange them in a fixed formation, choose their gear and targeting, then watch the fight resolve automatically.

Preparation has no timer. The board has nine tower slots arranged in three rows and three columns, plus three frontline slots. A hero’s row affects their damage and cooldowns, so positioning matters even within the fixed formation. You can assign targeting such as First, Strongest, Weakest, Lowest Resistance, Flying, Ground or Nearest before committing to a wave. Combat can run at up to 3x speed.
