What this is
A playable fan mini-game: drift out to scavenge debris, fight the constantly falling O2 gauge, and make it back to the coffin before it hits zero — the real game's oxygen loop in 90 seconds.
Three laws of scavenging
Inertia
Thrust adds acceleration, not position; release and you keep drifting. Braking beats accelerating for difficulty — the vacuum's first lesson, and this game's core feel.
Oxygen
2.6%/s outside minimum, scaling with speed; +26%/s inside the coffin radius. Red warning below 30% — at that point your round-trip must fit in half your remaining O2. The exact "one bottle" math from the real game.
Risk radius
Debris value rises with distance from the coffin (scrap 1 → circuit 7). Every far trip is a wager: O2 balance, drift-back time, thumb error.
Scavenger board (launch-week snapshot · for fun)
| Scavenger | Score | Note |
|---|---|---|
| @no_brakes | 486 pts | flew the whole round on a 10% oxygen margin — "red lights are suggestions" |
| @slow_drift | 441 pts | diagonal slow-drift only, seven round trips without a single gasp |
| @coffin_butler | 392 pts | docked every 15 seconds on the dot, never even saw the red warning |
Controls
Keyboard WASD/arrows to thrust; touch, hold the screen to drift toward the press. Free to play, no download.
Mechanic origin: the oxygen economy in the Beginner Guide and the value gradient from the Resource Atlas — the guide plays the game; the game plays the guide.
