The rule of thumb is that if its not on Waypoint its counted as a leak and against the rules to talk about it on the forums.
However there are clear shots of Meltdown in the new multiplayer BTS on Waypoint.
Plus we can see the name in the video as well, when they scroll through the maps. It’s probably safe.
Yes, but you can’t call it by name, or talk about anything in the map, or talk about playing on it, or mention that it was leaked, or mention IGN, or the words “melt” and “down” within five words of each other.
Otherwise you’re good to go!
