Koosmängu

Koosmängu, or cooperative play, is a category of games designed for players to work together toward shared goals rather than competing against one another. In a koosmängu, success depends on teamwork, communication, and coordinated strategies, while individual players rarely face direct elimination by opponents. The form spans board games, video games, and some role-playing experiences; examples include Pandemic (board game), Forbidden Island, cooperative video games like It Takes Two, and the Left 4 Dead series.

Key characteristics include: a common objective and a fixed set of rules; roles or classes that complement each other; limited or no player-versus-player conflict; mechanisms that encourage collaboration, such as shared resources, a single defeat condition, and turn-based or real-time coordination; and often scalable or adaptive difficulty to accommodate different group sizes.

Design considerations: designers balance difficulty to keep all players engaged, ensure effective communication, and avoid bottlenecks where one player controls too much. Accessibility and inclusivity are emphasized so players with different skill levels can contribute. In digital koosmängu, matchmaking, drop-in/drop-out participation, and online co-op enable play across distances, while couch co-op emphasizes social interaction.

Impact and variety: the popularity of koosmängu has grown with digital distribution and online platforms, leading to hundreds of titles across genres, from family-friendly co-ops to tense, story-driven experiences. The term contrasts with competitive or adversarial games where players primarily challenge one another.
