-Yoink- NEVERMIND JUST WATCHED THE VIDEO, THEY SAID ALL CUSTOM OPTIONS FOR GAME TYPES WILL BE IN IT. MY BAD. CAN LOCK IT DOWN NOW MODS 
I read the article here: http://www.gameinformer.com/b/features/archive/2016/05/09/exclusive-video-and-details-for-halo-5s-infection-mode.aspx
Now maybe I misread something but I didn’t hear anything about real custom game options…Aka changing the infected weapon.
Please somebody tell me I misread or something and they did say you’ll be able to, because if not…Well I’ll still be excited, but bye bye so many custom game types :’(
