Converting the plot from the console game to a cinematic scenario, seems like a no-brainer to me, if the players have not played it.
Anyone tried already?
Easy to do agendas based on characters from the game, even if you write out Amanda Ripley's involvement:
All with various cover ops, there to only collect the recorder, do a legal assessment, security, etc.
1 is after the a specimen for WY (duh!)
2 is from another company, spying/sabotage on WY.
3. One is there to do damage control & cover all traces, once 1 is done...
4. Finalize the take over of the station, implementing special orders.
5. Secure the location of LV 426.
Cut down on the digitial gamey running around opening different areas of course and make it a more sandbox-styled setting, letting the plot unfold that way. Plenty of interaction with charactrs onboard for roleplaying, with skill tasks to restart areas, find logs etc. Dilute down to a couple of key scenes/sets maybe, letting the players square off with limited resources against one deadly alien, testing their skill against various obstacles etc.
Set 15 years after Alien the Nostromo the flight recorder has been located/retrieved by salvage ship Anesidora, and is being held aboard Sevastopol, a Seegson Corporation space station orbiting the gas giant KG-348.
The team travel to Sevastopol, finding that the station is damaged and external communications are offline. They attempt to spacewalk into Sevastopol, but their EVA line is severed by debris, breaking of contact with the ship they came in.
While exploring the station, they find the flight recorder of the Nostromo, but the data has been corrupted. The players will also discover that the station has a single, deadly Alien creature lurking aboard. After run-ins with stressed survivors, looters and the station's Marshal, the plot will unfold. Interrogations of the captain of Anesidora, Henry Marlow. Finding out about that the salvage crew was able to backtrack the Nostromo's path to LV-426 and locate the derelict ship, containing a nest of alien eggs. Marlow's wife was attacked by a Facehugger, and was then brought to Sevastopol for medical treatment, but died after a Chestburster hatched from her.
Perhaps Waits will use the players to try to contain the Alien inside a remote module of the station, and then eject it into space. Although successful, Waits tries to eject the module with the team still inside.
While on the way back through spacewalk to confront Waits, the station's service androids abruptly starts to slaughtering the remaining crew. Attempts to interface with the station's AI, APOLLO, to cease the rampage. Further plots exposes with the find that Seegson had been trying to sell off Sevastopol to Weyland-Yutani, who instructed APOLLO to protect the alien at all costs. Then the findings in the reactor... followed by the released Marlow getting to the hidden Anesidora and the destruction of Sevastopol's orbital stabilisers, causing the station to slowly drift into KG-348's atmosphere. Time to get off site asap!
It would tie in nicely with the setting/lore, by explaining why the Space Jockey beacon stopped transmitting, adding details about WY's schemings, etc. The plot of the game is actually really good! Maybe have a look at the tie-in novel to find the relevant scenes/boxes to use?
