Mann Up Mode activated! I won't lie to you: you're going to die!
— The Administrator
Mann Up is the official version of the Mann vs. Machine game mode that allows players to receive items upon finishing a mission. The mode is accessible only by owning a Tour of Duty Ticket, a tool that allows entry into official Mann Up servers, which is consumed upon finishing a mission. A Squad Surplus Voucher is presentable as well, giving all players in the game an additional item upon completion of the mission, including players who did not present a Squad Surplus Voucher of their own. Like regular Mann vs. Machine, random drops are obtainable, and the Power Up Canteen is obtainable and usable. Any weapon is usable with no restrictions.
Tour of Duty badges
Tour of Duty badges or Operation badges are items given to players upon completing their first Mann Up mission in Operation Steel Trap, Operation Oil Spill, Operation Gear Grinder, Operation Two Cities, or Operation Mecha Engine. The badges are the Operation Steel Trap Badge, the Operation Oil Spill Badge, the Operation Gear Grinder Badge, the Operation Two Cities Badge, and the Operation Mecha Engine Badge, respectively. The badges are all-class cosmetic items that count how many missions the player has completed, similar to the Dueling Badge. Each mission that is completed is added to the badge's counter. Completed missions use the Tour of Duty Ticket, but uncompleted missions do not, leaving the ticket open for another mission. Missions that are lost or disconnected from do not use the ticket. Upon completing a tour, the tour progress is wiped, the Tour of Duty Badge increases its level by one, and another tour can be taken. Tickets are once again required for every mission of the tour.
