Put ISLAND.REZ in your main AliensvsPredator- Folder, just where the other rez-files are.
Launch the game, and in the start window, under options you type (or copy and paste this):
rez ISLAND.REZ
Make sure that you have disabled other custom levels, mods or changes (don't mean DM-Maps),
before you start with tis level.
that doesnt help much, because it doesnt work at all
so does eny body know how to run this tc??
english is not my native lang so I may make some mistakes
Try this - Install patch, put the rez file in the folder called custom (if it's not there it should be alongside the Movies, Save, Profiles etc folders). In options, enter the command line as follows
-rez custom\ISLAND.REZ
Then run the game and Single Player-Custom and the titles should be now there.
Uhm, shouldn't you be able to put it any place you want and just run the game using that parameter? Like making a shortcut for AVP on your desktop and then open the shortcut's properties and add "-rez xxxx.rez" to the file executed?!
