While Deep Rock Galactic has been in early access on PC and Xbox for some time, the game has officially launched and is now out on PlayStation as well. Not only that, but the game is also featured as one of the PS Plus free games for January for both PS4 and PS5. Deep Rock Galactic is a sci-fi co-op shooter where players will team up with other dwarves to complete mining expeditions while fighting off hordes of alien bugs and abominations. But despite the simple general premise, Deep Rock Galactic has a lot going on beneath the surface that takes some time to really get the hang of.
