Im currently trying to puzzle out what the titularMother MachineinThe Curious Expeditionstudio Maschinen-Menschs upcomingco-opplatformerrefers to.
Ah, the press release speaketh!
Probably should have read some more before I began exclaiming Chaos Gremlins!

Have an announcement trailer.
Her solution was to create a creature that she could take care of.
They are literally, canonically, emotional support Chaos Gremlins.
Mother Machine lets you enlist up to three mates in drop-in co-op to aid you.
The more gremlins, the higher the levels of both chaos and competition.
Platforming looks to be front-and-centre, but Maschinen-Mensch also refer to Mother Machine an an actionRPG.
Sounds like this manifests in mutation skill trees, which let you alter and improve your gremlins abilities.
The game also boasts endlessly replayable generative levels, although what this means in context, Im not sure.
The trailer above shows one gremlin farting on another.
It does look good though.
It’s out sometime in 2025.
