Died on the Endeavor lol

You can use the propane tank dropped by the machinist perk “Explosive Core” to damage yourself and even down/outright kill your character.

You can pause, go to loadout, open the perk grid and close it to respawn but it sure is fun to invite people to your ship and they walk in to see you dead on the floor lol.

May or may not knock people out of dialogue/the armory shop when shot next to them.
