Strategy two: What door?

Fun fact: Glaz can shoot through Castle's door. (And also through the airplane windows. He's the - only - character who can. Once you shot through them once however anyone can shoot through the now broken glass.)Anyways, in the event that you can't use our window tactic. Say the opponent is in the basement of a building. Your job will be the following. Pick the entry-way with the longest sightline. A lone hallway for example. That leads to a door which in turn leads to an important room or the objective room.Ideally, the room is filled with friendly cameras. If not, toss your own first and second camera in there (it's really important on Glaz to preserve your cameras.) And clear a way with your sniper of jammers and batteries if you have to. Either find a snug place in the room. Or pop in and out. At first, use mark to make your shots more accurate. Later however, it's much better to learn to judge angles to fire without needing a mark. Which takes a bit of practice. But is infinetly more useful. As most smart players will move when marked (though sometimes to the detriment of themselves.)Don't get too close to the doors. Lay down, and fire at the angles you see an enemy at. Even through a castle door. Obviously wood works just fine. In many cases, you'll snatch up one or two kills. And the enemy will be panicking, completely avoiding that side of the room. Or trying to find where the hell they got shot from (while calling you a hacker on all chat. Oh the salt.)Do NOT use holes in walls. IT'S A TRAP (burst weapons have a distinct advantage and they can actually see you.) A common myth is you can shoot through reinforced walls (thank you Desu Gun for testing it.)Two notes: I've found it extremely effective, but risky as well, to once you know the immediate area around a door is clear. Crawl up there and beat out the BOTTOM pannel and nothing else. Try to make it as square around the middle as you can. If enemies didn't notice the door, they won't notice from the corner of their eye that the area you can look through has expanded enough for your sneaky ass to lay next to (hence why it's risky. Anyone watching the door keenly will spray you to death.) and blast them with your much keener vision through your scope. Which is also why this only works with Glaz. Because you won't be able to see the contrast (and hence enemies) with the limited zoom and colour-saturation on the scope of most weapons.And two, the counter-strategy to this is, to once you know a Glaz is shooting from a corridor. Bum-rush him. Preferably from another angle. Most of the time, the Glaz will be there with his pants down. THIS IS IMPORTANT TO KEEP IN MIND. And why it's nice to play with a team that can cover you from such awkward... Mishaps.
