VR Training - Denver Offices | The Main Campaign - walkthrough MGR: Revengeance Guide

Another short mission, where your primary objective is to eliminate the enemy in the quietest way possible. Right after the mission starts, hide under the stairs - above you, there will appear a Raptor in a moment and, if you stay in your current position, it will raise the alarm. Wait for it to climb down the stairs and eliminate it quietly. After that, take to clearing the building - make sure that nobody spots you.

A manhole lid sticking out of the ceiling, covering a Data Storage.

After you have cleared the building, return to the location where there were two cyborgs and the Raptor. Look above and you should notice a manhole lid sticking out. Attack it (by jumping, e.g. off the bookshelf, to reach it) and a Data Storage will fall out. If you have cleared the whole building, Mistral should contact you after a while. She will provide you with further objectives.

Endurance Plus, dropped by the corpse of your double.

Return to the location where you have found the Data Storage and wait for Mistral to react ("Hurry to the objective"). A moment later, there should appear a marker and an enemy that is your mirror image. Defeat it and it will drop an Endurance Plus. After that, follow the marker that Mistral set for you, to complete the mission.
