A full “stomach” lasts for around 70 minutes realtime when the player is idle. The player uses more food when walking (1.5x) and running (2x).
If the player's Foodbar reaches zero, the player will suffer 30 damage to their health every 6 seconds until food is consumed (or the player reaches 0 Health and dies). Health lost through hunger in this manner is not restored after food consumption, the player will have to heal themselves afterwards using Medicine or a Medic Station
The foodbar can be replenished by eating collected or crafted Food items
