I’m not sure and maybe this is the wrong place to post this but since I bought Halo 5 last saturday I’ve been trying to access the experience page to get the weapon skin for the Assault rifle with no success. is anyone able to access the site or was it put offline at some point?
Looks like they have shut it down
Hey OP, site does indeed seem to be shut down now. Be sure check your PM’s 
I had not realised the site had been shutdown. That is useful to know as I often tell people to go there. Cheers for posting.
