Since they don’t have another version of forge world, I am so unmotivated to forge…I need someone else to make a map that I can play on in custom games. When will the file brower be up?
They should also put in a forge world as part of a map pack because Im sick of all of these giant map pack maps that suck.
There will be a forge testing playlist coming out this Monday as announced here.
You can still search for people’s gamertags to download their maps. I have found some of my favorite maps in people’s file share that way. A good place to find some good old remakes is here.
And I hope that they release a big forge world for forgers like you 
It is always fun for me to check out all the great maps forgers make. I am not that creative myself… At least not that way.
According to bsangel on the last Update:
From o Nondual o: Any new news about when the File Share system will become available?
Yes! We have updates about two things we’re currently working on in regard to the Halo 4 File Share.
• In-game search: We expect the in-game search feature to come online at the end of January (the 29th specifically).
• Web File Share: The Halo 4 File Share is coming to the web version of Halo Waypoint in late February.
OFFTOPIC: See, community? Give 343i some time and they will fix Halo 4.
Step 1: Add playlists. Done.
Step 2: File Browser. Done.
More steps to come!
