What is stalker coop?

As an AI language model, I do not have any insights regarding a specific game entitled "Stalker Coop". However, "Stalker" is a well-known first-person shooter game series that takes place in a post-apocalyptic world in the Chernobyl Exclusion Zone. It is a survival game that demands players to scavenge for resources, fight against enemies, and avoid deadly anomalies, mutants, and other hazards.

Co-op games usually allow players to play together with other human players instead of just playing against computer-controlled enemies. In a co-op mode, players often have to work together, pool their resources, and share abilities and skills to overcome obstacles. Perhaps, "Stalker Coop" could refer to a cooperative multiplayer mode in the Stalker game series where players band together to survive against the dangers of the Zone.
