The extraction is the entire game

In GRAIN ROT, getting out alive is the only win condition. There is no kill-based scoring, no raid timer, no objective marker. The elevator is the win condition.

The decision rule

Ask one question at every doorway: is the loot in this room worth the risk of a Corrupted closing the exit behind us? If the answer is no, return to the elevator.

Silent extraction

The Silent Extraction hidden achievement requires extracting while a Corrupted is within 10 meters of you without being detected. The community-published strategy involves:

• Throwing furniture as a distraction in the opposite direction.
• Walking (not sprinting) past the corridor.
• Avoiding emotes — emotes can distort audio cues and attract attention.

Specific detection ranges are 待确认 against the official 1.0 patch notes.

Inventory math

Your elevator trip is bounded by inventory. A full inventory means you cannot pick up the next high-value object. Beginners who run out of slots mid-room are the most common cause of failed extractions.

When everyone breaks

If every Vessel breaks, the run’s loot is lost for that session. There is no recovery. Plan extraction triggers before you enter a deep room.

Anti-grief use during extraction

• Block the elevator corridor with a broken body to bait the Corrupted.
• Throw furniture at a teammate’s Spark to launch them onto the elevator.
• Hover your Spark near a powered teammate if your own Vessel breaks near the elevator — your Spark can ride the elevator with the team.
