In this example, you can toast an opponent through a wall. There are many areas in the Complex where this is possible, but this one is good to know about.

Hopefully you can identify where this area is located. If you were to turn around, you would be looking into the red zone of the level. Ahead, you can see the dead end sniping spot near the ramps leading up. Anyway, plant a mine where I have the crosshair in the picture.

From that placement you can trigger an explosion as seen here.

Also, you can place mines on this wall on the left side which will cause a nice explosion on the other side, where I was standing in the first picture. The unfortunate part about these spots is that you don't get a lot of opponents hanging around here. None the less, a kill from this area is sweet.
