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 sort of unknown 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 and to eventually win the game. Each building's mission objective can only be completed once since it will self-destruct at successful completion. The only way to destroy the organic structures is by ground assault with a large and heavily armed X-Com strike team. Attacking the fungus 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, a brief is prepared outlining the mission objective so that each building can be disabled.
Once an objective has been completed a message: "Building has been disabled" appears. The mission completes if no more hostiles are present. X-Com troops can hunt down the last remaining aliens or escape via available blue-exit-tiles to force an end. There is no rush to escape! The alien building remains structurally sound.
When returning to the alien 'cityscape', the building automatically starts to collapse. Don't launch your craft immediately since they may be damaged from the still self-destructing building. Return to Mega-Primus at your leisure!
The Sequence
One building chamber can only be attacked at any time. Once one growth 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
Alien Squad Re-Inforcements
Aliens present within their structures are able to travel via their 'people tube' network. Any building which comes under attack by an X-Com ground force will prompt the alien horde into sending unlimited assistance to the beseiged building via the orange square-shaped devices found within every alien building battlescape.
UFO Patrols
Alien craft are grown and become active at the start of a new week. As the game progresses, more advanced UFOs will appear each new week. The alien craft will patrol their homeworld until a mission has been initiated. The chosen, active UFOs will travel to Mega-Primus and appear at the dimension gates. Many UFOs are grown, up to a limit, but not all will be sent across for a mission. Those which remain behind will continue to patrol ...until it becomes time.
X-Com craft which appear in their world will be mercilessly attacked.
