A dark multi level prison interior built around a central fighting pit marked by a glowing green circle on the floor. Rows of barred cells line the towering walls across several tiers, connected by metal staircases, catwalks, and railed walkways under harsh fluorescent lighting. The grimy atmosphere features stained concrete, scattered tables, a worn cell with a toilet and old furniture, and a dim exterior parking lot with streetlights and parked cars. Perfect for fighting and combat arenas, prison roleplay, horror experiences, escape games, or gritty survival maps.
