Oh boy, where to begin. I'll probably be the first of many to say this. Your new here, so Welcome to FH. Modded maps aren't allowed here. Also, your post is missing a few things to say the least. So, if this wasn't a modded map, you'll need pictures, a good description about the map and last but not least a download link to the map and gametype. I'm pretty sure you have one hour before this gets locked if you don't update your post. HERE is a link on how to embed your photos.
Basically what he said -_- With the name of the thread as 'halo mods', I don't think this belongs on Forgehub. And even if it isn't a modded map, you have to have a descirption/pics/DL link.
Oh lawl, as stated fix your post, there's guides on how to do that in the directory of this. Also, if your map does have mods then I recommend just leaving the thread as is and it will die out.
