The first and the third of these three campaign drafts may include xenos in some form - if you like. The main idea is to present ideas that should be possible to expand on in different ways. Hopefully it’s a fresh take on what Alien could be, without stretching to far away from the franchise core.
The U. P. P. crime syndicate
You work for one of the oligarchs in the Samarkand-Bukhara scrap cluster, a huge black market sector in space. The cluster consist of clunky spaceships and parts of old U. P. P. space stations. Here you can buy and sell what ever you like - drugs, slaves, androids, diamonds, minerals, exotic organisms or maybe an entire asteroid. The people who live in the scrap cluster are rough and corrupted; this is an autonomous part of the U. P. P. territories where capitalism is allowed to at least some extent. As members of a crime syndicate you need to deal with people from other syndicates, corrupt cops, android prostitutes, dodgy traders, war veterans and corporate spies. You might also need to navigate within your own syndicate; there is allways some Oleg or Dmitri who wants to cause you trouble. Maybe a xenomorph egg or an extremely valuable Engineer artifact will change everything for your syndicate - or the entire scrap cluster.
The Fiorina 161 Class C Work Correctional Unit
It’s a couple of years prior to Ripley’s arrival and the large facility is still full of people, most of them double-Y chromosome maximum risk prisoners. You might be one of them or you might be here for some other reason, perhaps as a corporate representative or a prison guard. Your days are long and often dangerous; accidents and fights between prison gangs are common. Most of you have secrets in some form, perhaps a hidden identity, a corporate agenda or valuable knowledge about the facility itself. Sometimes new spaceships arrive with new prisoners, a new warden, curious scientists or corporate representatives looking for info or just more profit. At some point, you will probably try to escape or leave Fiorina 161 in some way. How will it be done? What do you need to get away? Where will you go? Who or what will try to stop you? How will The Company react?
The Space Nest
You are a part of a big corporate expedition and you have just made a sensational discovery: a partly fossilized and partly still functional Engineer spacestation. Or what is it really? Nobody really knows what you have found. It looks like a gigantic, grey wasp nest, surrounded with large clouds of debris. It’s possible to enter the nest, and it’s full of bizarre chambers and strange artifacts. Of course, the discovery is a huge thing for both your expedition and The Company itself. Some of the artifacts found by crew members disappear and some people are getting murdered. Perhaps there are spies among you? Are you the spies? More corporate representatives are on their way, maybe even from rival factions. While more people arrive, the Nest itself starts to change. The presence of living organisms seems to have activated something. Could the nest be controlled or is it controlling you? Is it a part of a much larger system? A system of what? What first seemed to be a major discovery in the history of mankind might end up in a disaster of enormous proportions...
Edit: I just corrected a couple of language errors.
