Realm

Tactical auto-battler

Realm is a free-to-play, open-source tactical arcade game for PC, built around community-made modes. Its featured launch mode is a multiplayer auto-battler: you draft an army, arrange squads to counter an opponent’s formation, then watch the units fight in real time. Quick multiplayer lobbies and custom match sizes with friends are supported.

There’s no complex base building or micro-heavy routine in this mode. The focus is on army composition and positioning, with battles that can show hundreds of simulated units on screen at once.
