About GCoIIS.
DISCLAIMER: This is not nearly finished. There's not even gameplay yet, as I am working on the frame of this monstrosity. MORE IMPORTANT DISCLAIMER: THIS IS THE OLD VERSION OF GCOIIS WHERE THE FRAME ISN'T EVEN MADE. HERE IS THE NEW VERSION THAT IS CURRENTLY BEING BUILT: https://www.roblox.com/games/134448284254162/Great-Citadel-of-Infinite-Intensity-Scaling The Great Citadel of Infinite Intensity Scaling. Located inside of a volcano in the realm of impossibility, where nothing but lava and rocks stretches seemingly endlessly, this obstacle course is sure to contain the easiest along with the most difficult aspects of roblox obstacles. Inspired by: GCoHD (Abandoned), & GCoCIAND:R (WIP). Tools are provided, however the sheer number of parts here may interfere with the performance of lower-end devices. I cannot fix this, and I apologize for the possibility of very laggy gameplay.
