How do I remove the horizon in the GE?

I am making an FPS game and the horizon color (default blue) looks rather ugly and it seems to block the player’s view so he can’t see in the distance. How do I disable it or set it to stop blocking the player’s view?

Thanks.

There are two things you need to do. You need to change the color of the sky inside the World buttons (F8) and you need to lengthen the clipping distance on your camera. Select the camera, go to the Editing buttons (f9) and lengthen the distance of the clip end. You may also want to consider working at a smaller scale.

That worked. Thanks mate.
