It's been 1660 days or 4 years since the game have been released, you guys haven't update like you abandoned this game after the success of OTR Open World...Your game will be popular, my suggestion is you need to make a bigger map, an unique stories, add day/night cycle like OTR, multiplayer mode that we can play with friends or co-op, a new building mode so that we can build our base and mostly we could shoot the zombies with a gun in our hand. This game is more than perfect, cheers mate
