I-CON Arena Three vertical layers. One objective. No safe corners. A close-quarters tactical arena built for aggressive multiplayer gameplay — main floor, dual-tier catwalks, and an underground tunnel network all feeding into the same contested space. Ten ladders, nine tunnel grates, and 24 catwalk supports keep movement constant and rotations punishing. The central tower owns the map. Take it or play around it — either way it dictates the fight. Corner bunkers, 28 crates, L-shaped clusters, and striped barriers reward smart cover use, while alcoves on every wall keep flanks alive. Emissive blue, red, green, and orange lighting zones the map naturally. Fog keeps it atmospheric. 633 named mesh objects, 20 PBR materials, clean glTF 2.0 binary. Engine-ready, no external dependencies.
