Hello all,
I was recently waiting on a new 360Haven buddy to mod my Halo 4 gpd file and started playing around with Horizon while I waited. I found that you can now unlock all the same things if you are a Horizon diamond member. No jtag or hex editing needed. I'm sure I'm not the first to figure this out, but wanted to let the Haven community know if they didn't already! Have fun modding!!!!!
