Now all you have to do is head on over to the custom multiplayer menu and jump straight in. The game will let you know once the download has finished. Select the one you want, then click the “Download” button below the picture in the middle of the screen. Press the “Select” button below the big icon, and you’ll get a list of all their shared files. Everyone has overshields and damage resistance (MCC Max Helath 400) and starts with shotguns and Assault Rifle (or Rocket Launcher if you want to make things interesting) with halo classic guns on map. Choose that, then click on the map variants icon – the one on the right. Halo CE: Blood Bucket: N/A: Tanner: It's called Bloody Bucket. Once their profile shows up, the second option from the top will be “File Share”.
Enter their name in the box that pops up (capitalization matters here). Click on the little head icon in the upper right corner, then on your gamertag. Once you know the gamertag of someone who has your favorite map in their file share, you can start the game. As a complementary resource, you can use this spreadsheet, in which members of the community list the custom maps and modes they know of, as well as info on who made them and who currently has them.
