Those old Halo maps aren't getting lost to the sands of time. Starting August 12, Halo: The Master Chief Collection will hold a one-time file share to bring your old game types and maps forward to the Xbox One and PC, letting you replay them on modern systems.
This is a one-time service for maps from Halo 3, 4, and Reach, and you need to opt into it before the process kicks off. A post on the Halo Waypoint forums runs down exactly what you need to do, and we'll also break it down here. To ensure your files transfer over, you'll need to make sure you've taken care of your game types by 10 a.m. PT on August 12, and your maps by 10 a.m. PT on August 26.
- First, load up each Halo game on either an Xbox 360 or on Xbox One through backwards compatibility.
- Make sure the local files you want to transfer over are uploaded to your file share
- Simply leave them there! On August 12 and 26, 343 Industries should be able to handle the rest.
These won't be immediately available, but 343 Industries says it's aiming to have availability coincide with the launch of Halo: Reach on the Master Chief Collection. As for other files like screenshots and film, the studio did not find a "workable solution" but they're still investigating a way to bring screenshots into Halo Waypoint, so you can download them.
Halo was a staple of late-night splitscreen sessions on the Xbox 360, and custom maps were a tradition, at least in my group, as a way to wind down. Setting run speed to high and giving everyone swords, or a closed-off area with random heavy weapon spawns were a way to cool off after a long session of Halo, and it's nice to see that they might not be lost forever on my 360's hard drive.
The Master Chief Collection is set to come to PC sometime this year, though no specific date has been confirmed yet. As-is, it's an embarassment of riches and with Reach on the way alongside all those old custom modes, it'll grow even larger. We'll keep an eye out for when this will actually land, and how well the file share goes, as the year goes on.
