A cartoon hillside built entirely out of checkered green grass blocks, with mushrooms the size of buildings growing out of every ledge. It reproduces the Mushroom Hill stage from the Sonic games: red-capped and blue-capped mushrooms on brown stems act as platforms and roofs, giant tree trunks rise past the edges of the level, gold rings hover in rows over the paths, and the sky is a flat bright cyan. One shot looks across the terraced hill with mushroom caps stepping down towards the camera, another sits low among blue mushrooms and small candle-like sprites, a third climbs a chute between mossy walls, and a fourth shows a signpost and an item box beside a rising ramp. Nothing here is meant to read as a real place, and the checkerboard texturing is applied to the ground as much as to the props.

The level covers 6832 × 5728 × 1728 map units. Sixteen spawns per side hold 32 players. There is one bomb site, no hostages and no rescue zones, and buy zones are present on both sides. A HE grenade, a kevlar vest and a TMP lie on the ground. Geometry is heavy for a custom map: 7,729 faces and 44 textures, all 44 embedded in the .bsp, more than the 6,262 faces of de_aztec. Of the 563 entities the bulk are 392 env_sprite objects, the rings and glints scattered through the level, with 12 breakable objects, 10 ambient sounds, two ladders and one illusionary brush. The sky is the mushroom texture, and the archive installs three sound folders, six sprite folders and a radar overview alongside the map.
