The Tour of Duty Ticket is an item that allows entry onto an official Mann Up server. This item can only be redeemed in Mann Up Mode and is only consumed upon successful completion of a mission. If the mission is not beaten for any reason, the ticket will not be consumed and can be used again later. Tour of duty tickets are not consumed if the player plays a already-completed mission, and otherwise are only "usable" once. Tour of duty tickets are bought from the Mann.co Store or from certain crates.
