The level takes place on the rooftop of the Citadel in the previous level.
The level is surrounded by a red barrier and has multiple Tetris pieces surrounding the middle of the arena. In the air, there are large Tetris pieces and a large Rubix Cube in the middle. The ship can be seen flying in the background.
In one corner of the map is located an (yellow) O, (dark blue) J, and (sky-blue) I tetromino stacked on top of each other. On the very corner on top of the I-Tetromino is the hidden coin.
Near the same side as the hidden coin but in the other corner are four tetrominoes stacked on top of each other. There should be a (dark blue) J, (orange) L, and two (sky-blue) I tetrominoes; with all of the tetrominoes forming a small gap inside the J, L, and one I tetromino. Look inside the small gap for the hidden gem.
There wasn't any hidden currencies in this level originally, making it the first campaign level to not have any hidden currencies. However, in one of the updates around V 16.5.0, the hidden gem and coin were added back.
There are 45 enemies in Easy mode. However, in Hard mode, there's 50.
This is the first Campaign world wherein you are not permitted from using your own loadout you so desired. Instead, you are given six weapons of each type. Also, gadgets are not permitted to be used in this campaign level as well.
The blocks surrounding the arena are tetrominoes; the colors are a direct reference to Tetris.
