There are??!
The ASTmod was started by Atrocities and since I've kidnapped him, its now being supported by CNCRaymond. The website is
ASTmod.
The Star Trek mod is a project by Atrocities and myself. It isn't available yet, but perhaps one day soon. The link for the website is in my signature.
The biggest difference between the two mods is the depth, the ASTmod is more liked regular SE:IV, while the Star Trek mod is more of a 'complete' conVersion.
