The UI in Metal Gear Survive provides vital information for your survival. In the top left, you'll find your Health Bar (red), Stamina Bar (yellow), and Oxygen Bar (blue, only visible in dust zones). Below these are your Hunger and Thirst meters, which deplete over time and require constant management. Allowing these to drop too low will result in negative status effects and eventually death.
The bottom right of the screen displays your currently equipped weapon and item, along with their ammunition or quantity. The mini-map in the top right shows your immediate surroundings, enemy locations (if detected), and objective markers. Pay close attention to the various icons that appear on the mini-map, as they indicate resources, enemies, and points of interest. Regularly checking your UI is crucial for making informed decisions and staying alive in Dite.
