Project IGI Easter Egg - The Half-life Scientist

Start the 6th mission, where you are to kidnap Jach Priboi.

When you are inside the first base, there are some unarmed people talking beside the jet.

To get a good look, i recommend using the binoculars, since they cower if they see you.

The man closest to the power station is a copy of a half-life scientist, down to identical clothes.
