3 gel + 3 quick fire baterangs
/\/\/\ yep. if you are talking about the 3 on top of 3 divided by fences then that is how to do it. gel the bottom 3 sit near the middle on the fence, exposion+quick fire = trophy.
Some can be as simple as running across them to the end. Others, not so much. That's the beauty of it imo.
The six switch one was the toughest for me, which gives you an idea about how truly easy they really are.
