Crushed Rock

Crushed Rock is an element in Oxygen Not Included that is primarily obtained from space missions. It appears as a resource that players can bring back to their colony by sending rockets to certain planetary destinations. In the base game it is found on the Dry Planet destination in the starmap; visiting that biome yields Crushed Rock as a collectible resource.

The ability to acquire Crushed Rock depends on the game’s rocketry systems. The Rocketry Upgrade / Spaced Out! content introduced rockets, rocket modules, mission destinations, and supporting buildings such as the Command Capsule, Cargo Bay, Canister Filler, Canister Emptier, and various reservoirs and cargo tanks. Players must construct and outfit rockets, select a mission to the Dry Planet, and return the cargo to recover Crushed Rock. Since the base game and expansions now share a unified codebase, downloading content unlocks access but the underlying rocket mechanics are part of the same binary.

Practical points and interactions:

• Acquisition: Crushed Rock is obtained on the starmap by sending rockets to the Dry Planet mission destination and recovering returned cargo. Ensure your rocket has an appropriate Cargo Bay (or compatible cargo modules) to bring resources back.
• Requirements: Building and launching rockets requires rocket modules and supporting infrastructure added by the Rocketry content (e.g., Command Capsule, Gantry, fuel tanks, and relevant research). Use the Canister Filler and Canister Emptier for bottled gases and Gas Cargo Canisters when planning multi-resource hauls.
• Integration: Because Crushed Rock is a space-gathered resource, plan missions with return capacity and consider mission hazard and fuel costs. The Rocketry Upgrade also added new UI screens for managing missions and destinations, which help plan collection runs.
• Availability: The Dry Planet is listed as the source in the base game; acquiring Crushed Rock relies on repeatedly visiting that destination or unlocking it via mission progression and relevant codex entries.
• Strategy: Combine Crushed Rock retrieval with other valuable mission returns (new elements and critters introduced with the rocket content) to maximize each flight’s utility. Use rockets’ cargo management to prioritize Crushed Rock when storage space is limited.
