STALART is an online game built around an atmospheric open world inspired by the dangerous, mysterious Zone. Players can search for artifacts, complete quests and dungeons, hunt mutants, and explore unknown territories. The game also offers trading and mercenary activities, with opportunities for players who enjoy both player-versus-environment challenges and competition against others.

Social play is central to the experience. Players can form or join factions, assemble teams for expeditions, and make friends or rivals in a world where other stalkers and bandits are controlled by real people. The setting features lethal anomalies, mutated creatures, and energy surges known as emissions, which threaten life across the Zone. Players can also venture into the previously inaccessible northern region to face new dangers and uncover its secrets.

STALART provides account registration for access to a personal account and requires players to download and install its dedicated launcher to play on its servers. The game is designed for exploration, survival, cooperation, and conflict, with a wide range of activities for different play styles.
