Maybe Merged with Core World Page.Edit
A final endgame zone, a heart of infection.
Here the player must brave mighty enemies, and face the Essence in an attempt to stop the infection. The essence can never truly be defeated (if this game does end up an MMO), but when you destroy its form, you hurt the infection everywhere, and gain valuable data.
It starts with the player landing on a small rock underneath a massive vortex. They enter the vortex, and battle his/her way up until he/she reaches the eye of the storm. Here he/she must stay on a small asteroid platform and move throughout the dark conduits and corridors, attacking the Essence.
