If you preordered Metal Gear Survive, you’ll be treated with a few bonus items that you can redeem within the game itself. However, you’ll need to finish the game’s prologue before you can actually get to them. Simply start up the game, and keep playing through the main story until you reach the base camp. Virgil will inform you that you need to get food and water, and once you have control of your character again, head to the Repository nearby.
Interact with it, and choose the Supply Box option at the bottom of the menu. Here, you’ll see a full list of items you can grab. These are your preorder DLC items. Simply press the square button (or X if you’re on Xbox One) to take all the items at once.
The DLC items include recipes for the following items: Bat (Gold), Sledgehammer (Gold), Survival Machete (Gold), Survival Spear (Gold), Survival Scarf (Metallic Green), Survival Scarf (Metallic Blue), Survival Scarf (Metallic Pink), Survival Scarf (Silver), Boxman (The Orange), Metal Gear REX Head, Metal Gear RAY Head, Bandanna, and the Eyepatch.
And that’s all you need to know about getting your preorder DLC items. Be sure to search for Twinfinite for more information on Metal Gear Survive.
