Darwins Trash

Darwins Trash is a single-player puzzle shooter set in a randomly generated cave. You shoot your way through its rooms, face foes and tricksters, encounter helpers, and search through piles of loot for the trash at the cave’s heart. Each playthrough differs, giving you reasons to return and discover what lies inside.

You can find valuable items as well as junk. The game also includes quests, achievements, leaderboards and high scores.
