Here's word on this roguelike created by a solitary developer: "The year 2476, Earth's space-federation has been building moon-bases across the galaxy. One of those moon-bases has been sending a distress signal. Space Grunts are a group of intergalactic "problem" solvers, sent to investigate.." A short release trailer from last week offers a look.
