I think yo mess with shield doors as the person above me said. There are cool things you can do with flares, reginerators and shield doors. Try looking through it from the side.
you think it avalanche cuz i think it looks like blackout from the floor design. anyway, i dont know how to do it but its an awesome pic for sure!
I found one way to make the dog tag pictures. first you need to be in a party of two, and be the host. You have to do the spawn point glitch so your in a box. after you have that set up put turn the box to not spawn at start and then place a shield wall (yellow power walls) somewhere inside the box. once you start a new round and spawn in the box you need to go near the shield door and jump or run around it, whatever gets it to lag and allow the center to become clear. You will notice this when you dont see the yellow glow, but instead the black ground with a yellowish tint. Its only for a few seconds so have your weapons ready, or your *guy* ready for the screenshot. You can then go into theater and fast foreward to the time where the shield door comes up clear. I cant explain it very well but i will come up with a detailed tutorial later. But be warned, not every time are you allowed to view the clip, sometimes i get an error saying it cant be viewed. I dont know if its related to the lag or what, but just FYI
