Mvm map set in an open-pit mine with classic dustbowl theme.
The layout is experimental twist to gate map. The gates are not placed along the main bomb path. Instead, each gates have their own bomb path which converges with other paths. Also all spawnpoints stay active throughout the wave regardless of the state of the gate.
Each gate adds an additional bomb and because of how the paths converge, players are forced to retreat if they lose the gates.
