I spend a lot of time playing custom games with my friends. After a couple hours or so, people start leaving and eventually we’ll have 5-6 people left. I got to thinking, what if we could join random Custom Games happening on Halo 4 at any given time? Then Custom games could keep going. When your friends leave, randoms can join and you’ll have a full lobby of 16. I just think its a cool idea and I think 343 should try it out for a bit.
Truth.
That is a briliant idea 
You, you there OP.
You work for 343 now.
Go make more good ideas.
I’ve been having that idea since Halo Reach. Custom games were alot of fun back then. Now in halo 4 i rarely play custom games -.-
YESS!! that way you can search for awesome zombie games!! GENIUS GENIUS GENIUS!
I already brought up the idea of a Custom Games browser a very long while ago. It wouldn’t work though. See: Battlefield 3
This has been discussed quite a few times. A feature like this would definitely be needed in Halo 5.
