Would it be fun to be in simulation of Attack on Titan? YES! A friend suggested that I make a blog post about this. The game is on it's early stage and it doesn't have an official name yet but it's playable for fans of AoT. Players are also looking forward to a multiplayer mod within the game which is going to so awesome!
