The Can of Tuna is found in food crates and ration boxes that players will find while running the roads or cleaning out monument sites and points of interest.
The can of tuna provides a good amount of calories and hydration in RUST when compared to other food items.
While you can only find these cans at the monuments, you pick them up in pairs. They make for a handy refresher while you’re out farming for scrap.
If you’re struggling to find enough tuna cans to light up your base, you can buy them from the Bandit Camp Shopkeeper for 5 cans per 10 Scrap.
