What's to explain? That map file is not for the Republic Commando the PC game, it's for this game
, a crappy little game for Cell phones with a non-canon story about Delta Squad killing Jedi during Order 66.
Install map to your Maps manually, just copy and paste.
All numbers in the brackets must match for this to work correctly. Have fun and enjoy.
That is not how you install a mod map onto a PC game, it is a little more complicated than that. There aren't any SP mods for Republic Commando on the PC because the proper tools haven't been released, so stop going on about it nub.
And don't misquote me. I didn't say "But its okey" (I can spell.) I simply said, It's not great.
