None of the other sp missions, like Lumoria or Covert Ops, overwrite the main campaign, only CMT SP and the H3 style, at the moment, as mentioned, do overwrite easy way to see if they do overwrite is if they simply have the same file name (a10,b40,c20 and so on). They only overwrite the universal ui.map file and the Universal UI is designed to support them and many others. Its required for many external mods like SPV3 and adds quality of life. Step 4: Might as well get Open Sauce mod. Then just drag everything into the games map folder. Here's one HR-Firefight-Airlock_v2 (you can have your multiplayer menu open which lists all available maps, even greyed out ones, so you don't need to memorise).Īlso, if you download missions I've mentioned like Lumoria, or other campaigns mentioned in the Links and Useful Information.txt which comes with the Universal UI, then as long as you have the Universal UI, you do not need the other UI.maps which come independently with the other downloads like Lumoria. Step 3: Since Custom Edition is by default multiplayer-only you should download the single player maps + UI. These also go into your maps folder, and only work once you've installed Open Sauce, which only works with a legitimate copy of your Halo Custom Edition, meaning you installed it with a legit installer, had your CD-Key inserted, and updated it to v1.09.
With Open Sauce, Developers have been able to implement further visual and even gameplay features into their maps, Like CMT is doing with SPv3.
