Alien Dimension (Apocalypse)
The Alien Dimension consists of a bleak,hostile environment with an organic city. This city undoubtedly constructs Alien craft and nurtures the Alien brood. The structure of the buildings is immensely strong, but there appears to be weak point which will allow our Agents and vehicles to gain access to the building south of the dimension gates. If we can research this building further then we will have the necessary information to send in our squads to destroy it. We should then be able to gain access to the next building via the organic tubing that joins the Alien city together like a giant umbilical cord. From: Apocalypse Ufopaedia
The Alien Dimension
The alien's home. The environment is bleak and hostile with invunerable 'buildings' with an irregular snaking chain-like umbilical acting as a people-tube connection between alien structures. The buildings are of organic design and seem to be overgrowths of some exotic fungus.
The Dimension Gates allow free movement of UFOs at any time into Mega-Primus.
UFOs will be on active patrol within their world. Any threats will be attacked by all alien craft
Organic Structures
There are ten structures which will need to be destroyed to prevent Earth from being infiltrated. Each building can only be completed once since it will self-destruct at mission completion. The only way to destroy the organic structure is by ground assault with a large and heavily armed X-Com strike team. Attacking any organic growths with craft weapons does not achieve anything.
Each oversized fungus must be researched to understand its purpose and importance ...and when troops have landed at each growth, knowing what needs to be done to disable the building.
The Sequence
One building chamber can only be attacked per visit. Once one building is destroyed, a new research topic becomes available back in Mega-Primus.
1. Sleeping Chamber
2. Food Chamber
3. Alien Farm
4. Maintenance Factory
5. Incubator Chamber
6. Control Chamber
7. Spawning Chamber
8. Organic Factory
9. Megapod Chamber
10. Dimension Gate Generator
