Arowana Mall is a map for the game Splatoon. It features tightly closed areas as well as closed-off areas that are perfect for covering with the roller weapons.
Arowana Mall is full of tightly-closed spaces. The center of the map has a large hill. The map is sort of divided into squares. After spawn, there is a block down a ramp with its walls being alternate upper paths. They lead to paths to go behind buildings to the center hill. There are a few grates across the upper parts of the map that are above water, so Inklings must be careful not to fall off.
This is one of the 4 maps revealed in the initial E3 trailer.
