Divided into two teams, each five-member team - the cast plus guests Dohee, ZE:A's Siwan, and Yeo Jin Goo - consisted of a general, cart, horse, cannon and soldier, with the general able to rip the nametags of everyone underneath him or her. Each rank was able to tear the nametags of only those people who were lesser-ranked than that person. An exception was made for the lowest-ranked soldier, who was able to rip the nametag of the general.

A thrilling nametag-ripping battle ensued, and it was only Gary's quick thinking that saved the day as he disentangled himself from Kim Jong Kook's arms and tore off the general Song Ji Hyo's nametag in one fluid sweep, ending the fight and claiming the victory!

The final surprise, however, was reserved after the games had ended, when it was revealed that the fan behind this entire episode had been secretly watching the entire time! Posing for a final photo, the 'Running Man' cast and crew thanked their biggest admirer for one amazing episode.
