Hi guys - basically I need some help with finding a particular game that I never played but read about a long time ago. I believe that the game was called Alien, or Aliens, something like that. It was supposed to be the kind of point-and-click puzzle adventure game on some space ship. I don't think it has anything to do with the Aliens franchise.
I also remember that in one part of the game you had to cut of some dead dude's hand in order to use it to open a door or something.

I've spent a fair amount of time on google but haven't been able to track it down yet. I'd be interested in trying it now, so would be grateful if someone could remember its name!

Alien Virus ?

I don't know about cutting off a hand but i think there's using a hand of a corpse on a scanner.

I think that looks like it! Thanks a lot!

However, this springs to mind another game that I once played, and it's a shame that I don't remember more. Basically, it was another point and click adventure game and you started off on a submarine. I only played the demo and really liked it, unfortunately I don't remember the name. Any ideas?

That is it! Thanks a bunch guys! Unfortunately, I wasn't aware that I could only mark one of you as solution.

You're welcome mate, and don't worry about the virtual cookies ;)
