Could one kind soul download the updated Infinity Slayer gametype and put it on his/her file share? I do not have gold so yeah I can’t access the gametype.
List your gamertag as well, thank you very much! 
I played it earlier then shut off Halo, if it’s still in my recent files then I’ll stick it up for you. One moment.
Ahaa, you’re in luck. Here you go.
