The Megavents are a structural conformity among the Concordance Extraction Corporation-financed colonies.
A collective megavent was a massive circular subterranean network of catwalks and paths that stretched for miles whose main function was to accommodate planetside gravity tethers.
In correspondence with its environment, the Megavents are the first location reported as harboring the strange organic growth. The growth was initially reported by Cameron, the Megavent Supervisor of the Aegis VII Colony. He as well as future observers noted the horrible odor emitting from the growth as an outstanding factor. Cameron was eventually killed by a mass of this organic substance bursting through a vent soon after attempting to rid the Megavents of it by burning it off.
The colony maintained at least twenty seven Megavents:
- Megavent 12
- Megavent 24
- Gravity Tether 16
- Colony Life Support Power Room
- Megavent 27
- Noting Eckhardt's position as "Executive Director of Colonial Mining Operations," it is peculiar that when told of the existence of the Megavents, his first reaction is confusion as if he had never heard of them before. Though he was likely lying.
- The Megavents appeared in two of the three chapters of Dead Space: Extraction that took place on the colony.
