The left third of the arena, including red reload and red base, is approximately one metre higher than the right two thirds. The only ramps in the arena are the ones connecting these two levels, plus a small stub ramp between blue and yellow bases. No ramps go higher than the red base floor level.
Circles on the map near yellow base are stacks of 200 litre drums, too high to shoot over. Circles in other parts of the map are stacks of tyres. Dotted lines show moveable barricades. Positions marked are those that were used during Nationals. Half-height barricades (mostly near blue base) are marked "Hht."
