Deep Rock Galactic sends a crew of spacefaring miners into the caves of Hoxxes IV to extract valuable minerals and survive the planet’s hostile inhabitants. Its missions take place in procedurally generated cave systems, so routes and spaces vary rather than presenting the same fixed layout each time. Destructible terrain lets the team dig tunnels, alter choke points and reshape the work site as they go.
Four distinct classes give the co-op its defining teamwork puzzle. Scouts use flare guns and grappling hooks to light and traverse caves; Gunners bring heavy weapons and a protective bubble shield; Engineers defend with sentry guns and other explosives; and Drillers carve through rock with handheld drills. Combining these specialized tools helps crews navigate cramped passages and large caverns while fighting alien enemies. The game supports solo play as well as multiplayer co-op, with teams of up to four.
Between expeditions, the game offers progression through unlockable weapons, cosmetics and player upgrades, while its six seasons of additional content are described as free. Its distinctive appeal is the combination of class-based cooperation, improvised terrain shaping and hostile cave exploration.
