How does infinite ammo work for split-screen coop play?
Provided the host has the feature unlocked, the host can use infinite ammo, but if the second player does not have it they can’t use infinite ammo like the host can. I’m certain he/she can still play in this game, but must have it unlocked if the second player wishes to use infinite ammo. Would that mean the only way for the 2nd player to have infinite ammo as well is to play through the game start to finish with that gamertag “hosting” or solo and unlock infinite ammo for that profile as well? Pretty much, yes.
