The Final Test (Tutorial) Mission.
From the start, go to the right, jump over two fences and turn off the generator. Subdue the inspecting guard, take the disguise and dump the body. Go inside the base to find the projector slides on the table inside the reception area. Take them upstairs, and go put them on the projector, and then wait outside on the balcony. The KGB Colonel will eventually get the target and bring them to the projector. While they are talking, sneak to the power console on wall nearby and turn it off, then go and hide behind the crate. They will talk, Jasper will begin repairing the projector and the KGB Colonel will turn the power on, electrocuting him and unlocking this.
