Dereliction is a first person Co-Op Xeno-Horde Procedural Rogue-like Shooter:

endless Xeno bug hordes & endless procedural levels For PC, Mac & STEAMDECK

You wake up, crashed onto a barren planet. Around you there is nothing but hostile wasteland, battered by wicked wind and storm.
There is a lone outpost barely visible nearby. Crawling slowly, with oxygen low, you finally reach the open entrance. Within the doorway a ramp seems to lead down into an underground facility.
You decide you must enter this facility and hope to find a way to escape this wretched place.
But you feel that you are not alone.

Within this old derelict structure, filled with ancient machinery. The lights are dim. Your oxygen generators can barely fill your reserves. Your immediate goal will be to find a way to send out an SOS - to try to contact someone, anyone, and be rescued.
That is not the only thing you find when you wake up. You now learn why you had felt so uneasy; the Dross. A long-forgotten entity, lost seemingly for an eternity, with endless claws and endless teeth.
To survive – to escape – you will need to fight through the hordes of these enemies and find a way off of this planet.
Fight against the Dross. They are vicious. They are endless. They are always around you. They want only to consume you.
Fight through their endless world. There will be procedural generated levels, deeper and deeper into the nest.
It will be brutal. But your overpowering arsenal of tools and weapons will certainly help.
