Alien Dimension (Apocalypse)

Warning: Major spoilers in this section.

Description

Official Entry: "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."

Introduction

In order to win the Mega-Primus War it will be necessary to fight the aliens at their own home. First X-COM will have to perform the necessary research in order to build craft capable of operating through the Dimensional Gates. Then it will be necessary to engage and survive the fleets of UFOs on the alien dimension in order for ground strike teams to destroy the alien buildings. The first trip to the Alien Dimension will unlock it as a research topic and after X-COM scientists complete that next step of research it will be possible to research the first building and proceed to the first tactical mission on the dimension.

Orange Pad Re-inforcement Spawns

The orange pads allow an alien to spawn every 35seconds (SH). The lifeforms which spawn-in are chosen randomly from the available units found normally within this particular alien structure.

• The pad device has mis-matched tiles when viewed from overhead-battlescape-view.
• The timer is global for the battlescape. If multiple orange-pad-device-structures are present, the game will choose randomly which orange pad the new alien will appear at, every 35seconds. The timer is not seperate for each pad structure.
• Alien corpses may clog the pad if they were killed immediately after appearing (spawn-camping) and will halt further spawns. Avoid killing aliens until they have had a chance to exit the device and move away if 'farming' for equipment.
• Four-piece pad devices only use one pad as an active portal, the others are inactive. If the active pad is destroyed, then a random pad -may- become active but the orange-pad-device-structure is usually disabled once the active pad is destroyed.
• If bulk quantities of alien corpses are present, the oldest corpse will be removed from the battlescape and will not be recovered. Weapons and devices will not be removed if too many are present (the game will start to become unstable and may crash).
• Orange pads and the bolbus plant next to it are explosive. The structure above may collapse.

Equipment Farming

Raiding an alien building for agent equipment is possible if escape from the battlescape is chosen instead of completing the mission objective.

• The alien building can be raided endlessly and is a way to increase lax attributes of agents if not raiding Mega-Primus organisations.
• Spawning aliens are easily ambushed (caution when dying on the pad) since they appear one at a time and in unlimited quantity (every 35seconds).
• Using non-explosive weaponry (eg: Toxigun only) will prevent explosions from destroying dropped equipment. Picking up needed armaments and dropping them somewhere high up in a man-made tunnel safe will preserve your loot however, rouge aliens may throw an explosive into your stash if they find it.
