Like the title says I was anolyzing the e3 gameplay and came across something cool, When the pc moved the crosshair by the side of the red rocket gas station you can clearly see that there is a cooking station. So it's pretty much 100% confirmed that cooking will be present, And if cooking is present then why not a hunger system? (hardcoe Mode)
