There is one final preparation that you should start working on now: yourself! Get in shape because you're going to have trouble saving yourself if you're out-of-shape to the point that walking a few miles in a few hours would be a serious challenge. Now is the time to start. Most preppers have awesome bug out bags that they couldn't carry for a mile. Don't be that person!
Despite being marketed as a game with no pre-determined goals, Minecraft does have a basic structure, that of a scavenger hunt. While striving to build and expand their shelter, players collect various items and resources to add to their capabilities, attacks, and defenses, with many items enabling access to others. Over time, the player will travel to other dimensions to attain their goals.
Personal defense items – such as rifles and heavy firearms – are going to be increasinly hard to manage the farther you move from steady supplies. Ironically, it’s firearms that help acquire more food, provide personal protection, and deter others from attacking. In a SHTF scenario, heavy armament is only good within fortified areas. If you want to stay highly mobile, switch down to a .22LR polymer rifle such as the Savage survival rifle or similar. Lightweight, collapsible, and perfect for hunting game. Loaded with subsonic rounds, it can also be a lot more efficient than heading off a target with a loud 30-06.
