Solid Snake arrived at the church in 2014 and learned from its leader, Big Mama, the history of the Patriots and Big Boss's war against them, including the supposed location of his body. However, several Dwarf Gekko, disguised in a hat and overcoat, managed to infiltrate the hideout, alerting the Raven Sword PMC to their location. They eventually got into a car chase, while the other resistance members held off their escape.
