He abandons you on a road and that's it. You are getting into the Area 69 area and bring back the black project. You have to go to the control tower and open the blast doors. You have to avoid the searchlights but not shoot out more than 2 of them. You have thermal goggles to see the guards. You have to get in before 5:30am.

You start out right by body armor if you don't have any. There are guards at mid-level on all of the light towers, plus many walking around. It works best to snipe EVERYBODY so that you aren't spotted. Apparently nobody minds the dead bodies all over the place as being unusual.

If you do get spotted, you're told to use a vent to get into the building. In any case, there's armor up on the control tower to replenish with, and a red spot to use to open up the blast doors.

The blast doors are right in the center of the mound. The vent is marked nearby and you can shoot your way in through the grates. There's a heart waiting for you inside that room (with the blast doors on the other wall).

Go through the hallway and shoot the guards at the other end. There's armor up and to the right in here. There's also a minigun there. This area has bulletproof glass so you're safe here. Go downstairs to the little opening (not the red path to the left). Shoot out more guys in here. At the end of the path is armor. Now take a right and a right and you can see a radar room - you disable the SAM site.

Now go downstairs and over to the yellow stripey area. There's a grate below you - go to the end where the grate is up and go in for the heart and armor down there. Move along - there's more enemies to slay. Then move left - they say there's a keycard. Get the armor and then touch the scientist to get his keycard. Follow him down the path to the left and you're in the giant cylinder building. Work your way down all of the stairs, shooting as you go.

Grab the jetpack and fly on out, heading for the triangle. You can fire a weapon while flying, but you really don't have to.

Truth takes it from you, takes off and abandons you there. No respect or money or anything!

mission passed!

Your cellphone rings - Truth wants to talk to you again "in about five minutes". You don't have to go there immediately, though :)
