Often described as "Dark Souls with guns," this series features ruined underground subways, mutated creatures, and excellent 3-player cooperative gameplay.

The spiritual sibling to Metro. Games like S.T.A.L.K.E.R.: Call of Pripyat feature robust community multiplayer mods (like STALKER Belarus or Anomaly multiplayer sub-mods) that offer radioactive exploration, mutant hunting, and harsh survival mechanics.

One player can draw the attention of aggressive mutants like Watchmen or Nosalises while the other lines up critical headshots.
