    After you have completed the chapter in the boat, (this is after you have beaten the hunter chopper) and have entered the building, you'll meet up with Alex and doctor Vance. Follow Alex and she will give you the gravity gun soon.

    markiemark1112Did anyone else hit the glitch where the elevator door won't open? The doctor chick presses the button before the door of the elevator opens. The elevator goes down, and she just stands there looking at me....
