I want to put out my mod for Halo 2. When I compress my map to a RAR or ZIP, it is almost 100 MB. What am i doing wrong?

Mmkay, for one, don't use maps, make a patch of it. I recomend Serenity. Also, if you use Serenity 3.1, if will compress the patch itself (if you check the Zip box), and would be slightly smaller than if you rar'd the patch.

Edit: Here is Serenity 3.1.
