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.

Just a small note, this achievement is in the Half Life 2 game.

Did 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....

As soon as you get the Gravity Gun handed to you from Alyx, you will get this achievement.
