I tried before but I'm dumb and it gave XP to the person you heal and not you, I'll look into it again later but if I can't figure it out then I dunno- might just make gene research grant you sufficient amounts of XP instead or something.
Crafting meds should give you some XP for now.

wb the medics?

I've released an update that gives you small amounts of XP when steering the sub, its also shared with nearby crewmates because I don't know how to give XP specifically to Captain players, lol.
It has exploit potential in some circumstances but honestly I doubt people would just choose to stand near a Navigation Terminal and AFK over playing the game itself.

I'll probably add a passive xp gain near navterminal for captains if the game will allow me to.

Looks great! Any plans to add to the captain a XP upgrade?

oh my bad, i completely misread how the mod worked am stupid lol :P

think before you post

I tried but it's not possible unless I can come up with a workaround.
