Back in the day we used to add crazy stuff to custom maps like large donuts and things that were never supposed to be in a particular level. There was a useful set of tools to do this but I can't find them. Anyone still have them?
I found a solution! There's an open source project called Liberty which allows map modding for nearly all Halo games on the Xbox 360 (including Halo 4). There's also a thread somewhere on XPG (I think) about it from one of the contributors. Sent from Tapatalk
