Yeah, you weren’t that wrong, hehe.
2011 -> started out in UDK, but didn’t like the lighting and foliage at that time.
2011-2014 -> been with CryEngine, but with that engine we couldn’t really progress in terms of gameplay (docu too awful)
2014 June -> UnrealEngine4, and I hope we release it with that engine 
Anyway, let’s keep that thread clean, and related to the Twitch Stream today! Looking forward to it
