Games with extraction
Games With Extraction on Steam start with Deep Rock Galactic, Lethal Company, Teardown.
You enter a dangerous instance with almost nothing, fill a bag, and keep the contents only if you reach an exit alive. The run is not scored when it ends; it is scored when you leave, which makes the exit itself the hardest part of the level.

How extraction changes a game
Greed becomes the difficulty setting, and the player sets it themselves every few minutes: one more room, one more crate, one more corpse to loot. That turns the tension curve upside down — it peaks on the way out, when there is everything to lose and nothing left to gain. Death stings in a way a roguelite death does not, because the backpack was real and it is simply gone, so these games tend to run on shared voice and nervous laughter rather than on build optimisation.
