2137 (December 11)
The Torrens arrives at Sevastopol. Unable to dock, Ripley, Taylor and Samuels go EVA, but are hit by debris. Ripley is separated from Samuels and the injured Taylor. Avoiding the Alien, panicked and violent personnel and murderous Working Joes, Ripley makes contact with Samuels, then heads into San Cristobal to retrieve supplies for Taylor.
While there she inadvertently trips an explosive trap for the Alien set by Waits.
Waits eventually provides Ripley and Samuels with safe haven and gets Taylor treated. Ripley works with Waits and Ricardo (one of Waits men) to trap the Alien in the Project KG348 module. While Ripley is in there, Waits remotely seals it and ejects the module into space. Ripley EVAs back to Sevastopol. Samuels meanwhile goes to try and access Apollo to lift the communications lockdown. He succeeds at the cost of his own ‘life’, and Ripley discovers that Weyland Yutani had purchased Sevastopol and are making sure the Alien specimens are secured.
She discovers an Alien nest under the computer reactor core and initiates an overload to destroy. Some of the Aliens escape however. The core overload reboots all the systems and Ricardo thinks he may be able to get communications back up. Unfortunately the comms are locked down again, so Ripley takes an ambulance shuttle and docks with the Anesidora, upon which Marlow escape earlier taking Taylor hostage, hoping to get him to dock so Sevastopol personnel can evacuate. She finds a final personal transmission from her mother Ellen, explaining what happened on the Nostromo, shortly before Marlow initiates an overload. Taylor knocks Marlow out and tries to help Ripley stop the overload, however they’re too late. Taylor is killed as Ripley narrowly escapes on the ambulance shuttle.
The destruction of the Anesidora takes out one of Sevastopol’s orbital stabilisers and it begins to fall towards KG348. Ripley goes EVA to manually align the stations comms dish and contacts the Torrens to effect a pick up via the station’s towing platform. Once back inside she finds that Ricardo has been attacked by a facehugger.
Ripley makes it to the towing umbilical and disengages the docking clamp, an instant before she is mobbed by Aliens. The concussion from the emergency release of the clamp jolts her and the Aliens free of the umbilical and lands Ripley at the Torrens hatch. Sevastopol burns up in the atmosphere of KG348.
Back on board Ripley tries to contact Verlaine – only to find another Alien on board. She narrowly escapes into an airlock blowing the Alien and herself back into space.
After sometime adrift, she is picked up.
NOTE: Sourced from the archive logs found throughout the game. The dating in Isolation is generally fairly well considered with a couple of minor issues – the date the station was setup and transmission times. Sevastopol is supposed to be located in the Zeta Reticuli region of space. As Zeta 2 Reticuli is highly unlikely, it’s more likely in the nearby Zeta 1 Reticuli system. As of 2179, some 40 years hence, this region is still something of a backwater where transmission turnaround times are 2 weeks. Yet messages sent to and from the nearest WY office are about 24 hours, which seems way too fast.
The fact Sevastopol was founded in 2105, also begs the question of why Dallas didn’t take Kane there after they left LV-426 in 2122. Especially considering that’s precisely what Marlow did with Foster after their similar encounter.
The dates for the Tanaka messages were based around the @MikeTanaka2095 Twitter account that Creative Assembly used to promote the game. As the contemporary days and months don’t correlate with the dates in evidence in the game, they have been modified to fit using common points of reference such as the official date of the decommissioning announcement and the San Cristobal lockdown. For the full rundown of Tanaka’s tweets, check out the The Nostromo Files or the Twitter account linked above.
