It looks like a combination of a killball, teleporter, smoke, an invisible person, and weapons... I'd think you' have to shoot from inside the killball, teleporter, and smoke... then look behind an invisible dude so that the weapons appear out of all of it.. Just my theory though. : /
Just throw a nade while looking through the trail smoke and a teleporter in the backgroud. You're welcome.
What Black said, Next time you should really look through our guide section.. There is tones of guide for these type of text photos.
The smoke is the smoke comming out of the pipe on blackout, at an angle, you can do that effect. Wow, i guess Black Theorem cleared that up haha. Hes correct though!
