IGN guides you through the final mission of the ridiculousness that is Saints Row IV. *SPOILERS AHEAD* Having assembled the key, the Boss must select a team to help him transport it to CID so it can be inserted into the simulation, which will cause it to begin deteriorating. The first part of this mission is an on-rails shooting gallery, followed by a brief defense sequence before entering the simulations inner workings for an all-out assault with CID.
