Once all five orbs are lit, the Soul Cube is operational, which the Cube will respond with 'Use us!' A red blueprint of it will also appear next to the weapon hud when it is fully charged. The five orbs located on the sides indicate the amount of lifeforce it has absorbed. It can absorb the lifeforces of any fallen entity, demon or human, to make itself operational. The Soul Cube has the ability to sense death. It was either destroyed (sacrificing itself, and perhaps also freeing the souls imprisoned in it) or trapped within the portal in order to destroy Hell's only link to the human dimension.

He appears to be very tall, because his tomb is very long. 'The Hero' didn't seem to survive, since his burial chamber was found. With it, their single greatest champion, simply called 'the Hero,' (a take on the Doomguy's namelessness) took on the invading force singlehandedly and managed to seal the portal. Most of the survivors were sacrificed, and their souls were used to create the weapon that would turn the tide: the Soul Cube. With whatever conventional weapons they had proving ineffective at stemming the horde, they eventually devised a plan using their greatest innovation, which bordered on functional magic.
