Whispers Behind the Wall is a team-based asymmetrical horror game. You can take on the roles of either survivors or killers. Survivors work together to escape a mansion by searching for 5 keys or repairing a radio to make an emergency call. The killer is solely opposed to the survivors. The killer must locate survivors by their noise or skills and decide how to eliminate them.
As survivors, you hide from the killer and ensure certain actions don't make noise. You can also draw cards to find items in certain locations to prepare for combat. Most importantly, survivors search for keys or repair a radio to make an emergency call.
On the other hand, the killer hunts the survivors. The killer must plan their actions carefully: move, listen, spread fear, block doors, etc. When the killer encounters survivors, a life-or-death battle begins!
