Seems better and more promising than most Open-source FPS Projects I saw, that are usually *cough* Qwaek Clones *cough* and 90-100% focused on multiplayer. Now if it's intended to have some RP elements, then it's a really great idea in a area that sadly seems to be excessively focused on MP and "kill everything that moves just because of it" game projects(And some commercial FPS projects, although having some cheap stories to disguise this nature, also follow this same sad scheme)
I know it's creepy, but I always remind of System Shock 2 when I hear about playing on a ship with aliens... or of the Alien movies of course...
Looking closely on its history... it reminds me of Unreal too(crashed on planet, must escape), that was another old game I liked, specially cause the enemies were not just cannon fodder there.
