Unfortnately can't seem to launch this game on my 64 bit wine.
Error: Assertion failed: Count >= 0 [File:d:\build\++ue4\sync\engine\source\runtime\core\public\Containers/UnrealString.h]
I'm not sure UE4 things are self-contained and universal for this enough though I've managed to play some UE titles like Antichamber.
Maybe more of a wine problem than UE problem though.
Does it have a native export to Linux and mac?
