*I should ****ing sticky this because people nowadays are just stupid.
*First:
the downloaded mod should be on your desktop, and unzipped. *or the other place you save your downloads*
It should be named bloodgulch.map. No need the bold.
if it's not, just change it.Some mods also include bitmaps.map and ui.map. If that's the case, just do the same for both of them *but not change their name. or I will slap you with a banana.*
Second:
Find your maps folder which should be in your Halo Demo folder. If you can't find it, I will slap you with seabees.
Backup all the files inside (bloodgulch.map, bitmaps.map, ui.map, sounds.map, b30.map, etc.)
And put them in a new folder called <whatever you want but make sure you know what it is>
Now, when you want to play the mod, copy the bloodgulch.map (and whatever else there may be) and replace the original ones in the maps folder. NOT YOUR BACKUPS FOLDER!! NEVER TAMPER WITH YOUR BACKUPS!! OR I WILL RUIN YOUR FUTURE/MANHOOD/CROWN JEWELS/CHILDREN etc.etc.etc.
Third:
Make sure your mods are saved in another folder called <whatever you want but make sure you know what it is> preferably put in the maps folder for easy access.
Fourth:
PLAY HALO AND MARVEL AT OUR SUPERIORITY!! MAUAHUHAUAHUAHUAHUAHAUAAA!!!!
