Bunker Rats is a co-op PvPvE extraction game set entirely underground. There is no surface. Maybe there was one once. Doesn't matter. You live in a bunker now. You and your team share a home bunker with a crafting bench, an armory locker, and the kind of ambiance that says "nobody has seen the sun in a very long time." From there, you deploy into shared bunker complexes where up to three teams are all trying to grab the same loot. Think of it as competitive dumpster diving, except the dumpster is a concrete labyrinth and everyone is armed. There are no guns. Combat is melee only. Sledgehammers, machetes, crowbars, a sickle, a stale baguette. Whatever you can find or craft. Every fight happens at arm's length in a hallway where both of you can hear the other one breathing. Nothing says "I want your loot" like sprinting around a corner with a fish skewer. It's horrible. You'll love it. The bunkers themselves are also trying to kill you. Gas leaks fill corridors with green fog. Busted electrical panels arc across doorways. The longer your team sticks around looting, the more the complex falls apart. At some point you have to ask yourself if that third piece of scrap metal is really worth it. It's not. You're going to grab it anyway. If you die, everything you're carrying drops on the floor for someone else to take. Your money survives because apparently it's in a pocket nobody can reach. Small
