not sure if it's exactly "hidden" but here's a roguelike that I liked

Basically, you're stuck in space and have to salvage shit from other ships using drones. The game is played on a screen where you can give commands or pilot remotely. There's entities aboard ships that will try to attack you, and you MUST NOT let that thing board YOUR ship.
It can be pretty spooky, but mashing your drone inputs and watching them all working unison is fun
