Halo 4 is amazing, no one can deny that, but unlike in Halo: Reach’s infection, the survivors in the flood gametype are always yellow. Personally, I HATE that and on custom games me and my friends try to figure out if there is a way to change that. So I want to know, IS THERE A WAY!? If not, can that please be changed in a later update?
There is currently no way to change the survivor’s colors.
Any yellow infection should be brought to the attention of a physician.
