RealmRealm

Realm is an open-source, free to play, tactical arcade engine built to bring back the fun, chaos, and boundless creativity of classic custom arcade maps. Jump straight into the action with our featured launch mode—a fast-paced tactical auto-battler—or open the creator suite to sculpt, balance, and host your own custom games.

Featured Launch Mode: Tactical Auto-Battler

Step right onto the battlefield without complex base building or micro-heavy chores.

• Draft & Deploy: Assemble synergistic army compositions and position your squads to counter opponent lines.

• Real-Time Tactical Clashes: Watch massive skirmishes unfold with hundreds of simulated units on screen at once.

• Lobby Matchmaking: Jump into quick multiplayer lobbies or host custom match sizes with friends.

Classic Custom-Map Energy

Realm is built on high-performance RTS foundations designed specifically for community-made game modes.

• Massive Multiplayer Mayhem: Support for dozens of players in the same match and large-scale unit collisions with zero compromise on tick rates.

• Instant Feel & Pure Determinism: Server-authoritative netcode combined with client-side prediction makes de-syncs an issue of the past while maintaining strict competitive integrity.

• Self-Hosted Independence: Zero risk of servers shutting down and breaking your favorite game modes. Host your own matches anytime.

• Never Lose Old Maps: Built-in compatibility mode ensures that older maps continue to run smoothly even after a core engine update.

Every tool used to build official game modes is directly accessible to players:

• Full Terrain & Unit Sculpting: Place props, paint terrain, customize unit behaviors, and hot-reload changes live as you test.
