Spacebase DF-9 Wiki:Game FAQ

Q: How do I establish my first base without running out of resources and dying in the first few minutes?

A: The absolute bare minimum required to survive initially is as follows
 * 2x2 floor space Airlock room
 * One Airlock door exiting to space
 * One Airlock door exiting to another room
 * One Suit Locker
 * 3x3 floor space Life Support room
 * One Oxygen Recycler
 * 4x4 floor space Refinery room
 * One Matter Refinery

* note all rooms must be joined by at least one door/airlock door

Q: How do I prevent my miners from suffocating each other in the airlock?

A: There are a few ways to avoid this:
 * Build multiple airlocks. 3x2 floor space with one space suit locker is ideal.
 * Place your refinery a room or two away from the airlock.
 * Send your miners out at an interval.
 * The most time consuming would be to micromanage the door locks, lock the door whenever you fear the two miners may collide.
