Zero-K

Zero-K is a free, open-source real-time strategy game built on the Spring/Recoil engine. It focuses on large-scale battles with physically simulated projectiles, deep unit control, and extensive gameplay variety across singleplayer and multiplayer.

Key Features

• Physics-based unit and projectile simulation affecting cover, dodging, and combat outcomes
• Terrain manipulation (terraforming) including craters, ramps, canals, and fortifications
• Large roster of varied units with distinct roles and abilities
• Singleplayer and co-op campaign modes, plus survival-style PvE scenarios
• Multiplayer modes including 1v1 ladder, team battles up to large team sizes, FFA, and co-op
• Powerful in-game UI and advanced control tools (formations, queuing, automation helpers)
• Modding-friendly architecture with extensive community-driven content

Use Cases

• Competitive RTS play in ranked 1v1 and organized multiplayer events
• Co-op matches against AI or survival waves with friends
• Experimenting with modding, unit design, and gameplay scripting on a mature RTS platform

Limitations and Considerations

• The game module repository does not include all associated infrastructure, tools, or artwork sources; additional components are maintained in other project repositories
• Requires a compatible lobby/client or engine content setup to play

Zero-K is a long-running RTS project aimed at tactical depth and player control, offering robust multiplayer and meaningful singleplayer content. It is well-suited for players and modders who want a modern, community-evolved RTS experience with unusual mechanics like physics and terrain deformation.
