I made two versions one for players who use CE like me, and one for players who play the vanilla version of the game. The removal of the oxygen system is balanced differently for both versions, see details below.
I tried to make this mod highly compatible with any other mods by using the advanced tag modifying system from Slipstream manager. It replaces the crew, modifies the oxygen system start value, and adds/removes augments.
Vanilla version
Download: No Oxygen in Lanius B 1.0.ftl
To compensate the cruiser gets a 3rd and 4th Lanius crew member, instead of the human crew member, but the Emergenc Respirators augment is removed.
Details:
- Oxygen System removed
- Human Crew member replaced with two Lanius crew members
- Removed Emergency Respirators

Captain's Edition version
Download: CE No Oxygen in Lanius B 1.0.ftl
Base mod: Captains Edition needed (it's a great mod!), place in the load order below CE
To compensate the cruiser gets a 3rd Lanius crew member, instead of the AI avatar, and an AI avatar generator as an additional augment.
Details:
- Oxygen System removed
- AI Avatar Crew member replaced with Lanius crew member
- Added starting augment AI Avatar Generator
