Samus participate to a virtual project simulating a trapped cube, involving ability to fight, to orientate and memorize.

So it is Digital Cube, widely influenced by movies Cube/Hypercube/Cube Zero. For people who doesn't saw this movies : some people wake up trapped in a giant cube with multiples cubic rooms, with different color and numbers. Some rooms are deadly traps, like acids, spikes, sound pressure, etc. This hack is based one the same concept : 49 pain-in-arse square rooms. Good Luck to exit !
