Hey guys I wanted to tell you about this awesome Halo community website designed to make full-lobby Halo 4 custom games available to people who join it. FULL LOBBY custom games all the time, just like Halo 3! We’ve had a really fun time and we want more people to experience this. The Website is: http://halocustomgamerz.webs.com/ and it’s awesome. The creator/manager of the site aims to create a custom games community. You really don’t want to miss out on this. Join the clan and send a friend-request to KILL ME GUYS.
Thanks for the website link. There’s also www.forgehub.com that does a great job with forge maps and customs alike. They also test maps. Huge community over there.
