Players can request access on the game's Steam page. The game features 24 players, where some act as wolves trying to blend in while others are lambs aiming to survive. Players collect clues from crime scenes to identify the killer and can use various items for combat and strategy. The game includes a focus mode for enhanced awareness and a 3D audio voice chat for communication. Character customization allows players to choose unique characters with distinct abilities. Players can engage solo or form teams, and trailers and gameplay videos are available for viewing.
