# Grand Theft Auto: Vice City reference

There is an "Easter Egg" from Grand Theft Auto: Vice City that is in Vice City Stories, and it is in the exact same location. This time it is literally under construction. Go to the bridge that leads to Prawn Island from the east side of Vice City. If you are coming directly from the Ammu-Nation, it should be on your left. It is the VCN building. You can walk into the arrow and you will be on top of the VCN building. Walk up the ramps to get to the helipad. Once there, you should see that a part of the helipad touches the neighboring building. Run and jump into the window. You cannot see through the window; it is a wall that you can walk through that has a window design on it. If you hit it in the correct location, you go through the wall and see the Easter Egg from Grand Theft Auto: Vice City, only it is still being built. It is a red metal frame (like a building that is under construction) and has a construction arm that is building it. Also the stand that it is on has a sign that has a smiley face and scribbles.
