June 22nd, 2011. 9:30 AM, EST Red & Blue declare ceasefire, having discovered a technique to topple whole mountains. The process is a little glitchy and somewhat exploitive: backwall stone block placed underground leave sky tiles when removed, which do not support dirt above them. By building a wall from one end of the mountain to the other and then removing them to sky, the whole thing came down, at no danger to those inside. An outpost fell safely to the ground. In the third image we see a few strange blocks that became stuck in air.
