Infinite Time Zero Hour & Time Trial Cheese

This is a way to have infinite time on both version of the mission. Making it easy to complete the normal time trial triumph for the emblem. You need 2 or 3 people to do this. One host, and one person to alternate between the map and the inventory menu. This works the same as previous infinite time cheeses. This makes outbreak prime and the quarantine zone emblem a breeze. A really fun mission to do.
