Zombies can be a pain in the blocky derriere, can’t they? With their relatively new ability to break down wooden doors, players have been forced to use iron doors in all their buildings – or have they? Perhaps not. A zombie can break down a wood door, but it has no idea how a wood gate works. So you can quite easily put a gate directly in front of your door and zombie proof your house.
Reddit user GideonBarish posted a very useful tutorial on how to automate your zombie proof gate / door set up using a pressure plate.
