Data terminal

Data terminals are laptop/briefcase devices that were utilized by Desperado Enforcement LLC. during the 2018 Desperado Incursions. The Maverick agent Raiden, when undergoing missions against Desperado, managed to locate these devices, and under the Maverick commander Boris's orders, downloaded the data due to it possibly containing sensitive data.

Behind the scenes
VR Terminals, referred to in-game as data terminals, were devices that appeared in Metal Gear Rising: Revengeance. Although Boris implied when finding them that they contained sensitive data on Desperado, they are really just a way to unlock VR missions.

A Data terminal first appeared in the E3 demo for Rising, where Raiden was supposed to retrieve Desperado-related data as part of his drills, but after downloading it had accidentially drawn in a Gekko UG.
