Level 08: Nuke and Pave
Study the pictures in the walkthrough - in one of them you'll notice an interesting fact about the player. To get this "power-up" you'll have to go switch hunting and do some back tracking. A simple hint will suffice: a net level is based on a portion of this map, the center of that net level has a pillar. On this level, that pillar will rise up once activated by a switch found later in the level.
