The Castle Doctrine is a unique experience that places you in a scenario where you have no choice but to survive. You must stop at nothing to protect your family and the things that are precious to you. You start with only two thousand dollars, a wife and a few kids. The main objective is to build a home security system to protect your family and any money you have in your possession. Sounds easy, right? You might want to think twice; there’s nothing easy about staying alive in The Castle Doctrine.
