Well it could be even more realistic pretty tame for a building falling down and all.
Update: was just playing obliteration, and there's plenty of color in the map. It's pretty damn beautiful. I'm pretty sure it's just ash from the collapse that's covering everything, which is pretty awesome in my opinion.
And you have absolutely no chance to get of the building when it starts falling... You just fall over and die, even tho it's just shaking a bit :/
Would be cool to be able to jump ^^
thats is why i usally leave it when u start to hear the noise,creaking and feel the pre-vibrations xD
