Basic Info
Fuel is a combustible material that can be used to increase the lifespan of a burning fire. To add fuel, open the backpack and pick up the item you wish to use. Then drag it on to the highest point showing above the fire. Each combustible item will add a certain percentage of fuel to the fire. Large items such as sticks, planks and charcoal will add more fuel to a fire compared to smaller items such as feathers.
