The phrase indicates a category of cooperative action games, typically featuring two players working closely together to overcome challenges. Titles within this classification often emphasize strategic teamwork, shared objectives, and character synergy. Examples include titles with similar mechanics, themes, or gameplay experiences focused on partnership and coordinated efforts.
The appeal of this genre stems from its ability to foster social interaction, strategic planning, and shared problem-solving between players. Its historical roots lie in arcade co-op games and evolved into more sophisticated console and PC titles offering deeper narratives and tactical complexity. The benefit lies in the enhanced social connection and combined effort required to achieve in-game success.
