Please update this trainer. Updates are not so often anymore.
It's had 11 since my last post

Up until today and the launch of version 0.5.x most of the trainer options has worked.
at least infinite O2, Stamina, Health and jetpack/hover fuel.
so even when the trainer was on hold it still mostly worked.
(it even worked in multiplayer as long as you were the game host)
sadly it no longer does, so i do hope that it will resume in the near future.
but for now i'll just change the game world to set players to a manual "god mode"
I'm somewhat confused about Osiris: New Dawn, I see two games with the same name, like Osiris: New Dawn (Experimental Branch) which is constantly updating and the other Osiris: New Dawn, in which has had 2 to 3 update's since I've been playing it. I've been using the trainer on the Osiris: New Dawn and have tried it on the Osiris: New Dawn (Experimental Branch) which never worked for me. So which one is the actual the real game.
Experimental are beta/testing builds.
