Alright so for our pictures on this wiki. Let's uniform them into using only promotional screenshots, meaning that if we were to screenshot something like a gun. We would only want to post a picture of that gun. Make sure you edit the screenshot using something like MS Paint to cut out all the useless parts of the picture. We wouldn't need to see the wall or even the hud, just the gun.
Also, it just makes the wiki look a whole lot better if you take the time to edit the picture, or you could just post it on here then I'll edit it myself and post it.
