(a bit tardy, but better late than never)
Exits are to the left and right, flamethrowers can be found underneath the seats, and those plasma burns on the carpet are just cannon signatures from all the Shivans running around. Give them some food and they'll leave you alone.
There *is* a fix for the GF4...oddly enough, just run fs2_open with the -GF4FIX option. It ought to work. Have a look at this thread:http://www.hard-light.net/forums/index.php/topic,10610.0.html
As for running the game without the CDs, that can't be done without getting an Illegal Hack(tm), something that is discouraged around here. You can't play the movies with fs2_open anyway. If you want, you can edit the cutscenes table so that all the movies are configured for CD #2, and that way you won't need to change CDs. Just copy the movies from CD 3 onto the hard drive and the game won't know the difference. (Be warned: the movie files are BIG.)
*squints at username* Hmm... do we actually have another GIRL signing up at HLP?
What does that make, four total?
