ive downloaded mods off file front buit i dont know how to add them into the game. sorry downloaded
all you have to do is open the mod file and extract the mod to your halo maps folder, easy as cake and if theres ppf files hope you have ppf-o-matic so that you can apply them to the right file if this doesn't work well then, i have no clue what to do
When asking a question, try to add more details about ur inquiry. It helps the people replying to your message. Anyways, if it is a Halo CE map, just add it to your CE map directory. If for regular PC, backup your old map (That is very, very, very important. Don't forget or be lazy about it) and then replace the mapfile.
Now, the stuff you downloaded may have come with a Readme/Manual. Check that out. If that doesn't help, check if it is a ppf. A pff is a file type that you apply to the map. To apply the ppf, use ppf-o-matic like DoomGangsta mentioned. There is a manual on how to use ppf-o-matic, so I will sustain from explaining that.
OK did this guy join the Forums just for one question? W/e, he could have given details by now but he didnt.
