Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Realm is an open-source arcade engine designed from the ground up for community-created games. Because the platform relies heavily on low-latency netcode, determinism, and robust creator tools, we want to involve players and map makers as early as possible. Early Access allows us to gather feedback on our initial featured game modes—such as our tactical auto-battler—while stress-testing multiplayer lobbies and refining the editor alongside active modders.”

Approximately how long will this game be in Early Access?

“We anticipate Realm will remain in Early Access for roughly 12 to 18 months. However, development will be driven by community feedback, stability milestones, and the maturity of our map editor and scripting API rather than a rigid timeline.”

How is the full version planned to differ from the Early Access version?

“We plan to expand both the creator suite and the variety of playable arcade modes. For the full version, our goals include: A broader suite of built-in custom map archetypes (such as Tower Defenses, Hero Arenas, and classic RTS melee modes) alongside our initial auto-battler. Expanded AI-assisted editor capabilities to make complex map scripting and asset placement even more accessible. Streamlined map discovery, ranked matchmaking queues, and spectator tools. Native Linux and macOS client support.”

What is the current state of the Early Access version?

“The engine is currently in a functional pre-alpha state. Players can jump into our featured tactical auto-battler custom map to test army drafting, squad placement, and large-scale unit simulation in multiplayer and local testing. The standalone creator suite is live, allowing makers to sculpt terrain, configure unit stats, write C# scripts, test map logic via hot-reloading, and utilize our integrated AI creation assistant. Expect rough edges, balance passes, and occasional breaking updates as core features continue to evolve.”

Will the game be priced differently during and after Early Access?

“No. Realm is free and open-source both during Early Access and after the full release.”

How are you planning on involving the Community in your development process?

“Community involvement is fundamental to the project. Because Realm is open-source, developers and creators can inspect the source code, contribute pull requests, and track active issues directly on GitHub. We also maintain an active Discord server and community forum where players can suggest balance tweaks, report bugs, share custom maps and assets, and collaborate with us on upcoming engine features.”

About This Game

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.

Complete Creator Suite

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.

  • AI-Assisted Map Making: Stuck on scripting logic? Use the integrated AI assistant to prompt your way to a working map.

  • Open Asset Sharing: Share models, textures, sound kits, and gameplay logic with the community to remix and build new genres together.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:
