Just realised I posted a thread in the wrong section of the forums. Anyway, I re-made good ol’ Crazy Cannon’s from Halo 3 in Halo 4.
If you want to download it, click on this link and it will take you to my file share. Download the game-type and both map variants (If you don’t have Majestic DLC don’t download the Monolith variant).
I’m working on a version that has vehicles in it too, so hopefully it will be more like the old Halo 3 custom game.
