Fishing is actually not as simple as it might seem. Follow these instructions to have the highest chance of catching a fish:
- Equip a Fishing Rod and cast the line by left-clicking into an area with water. The red and white fishing float/bobber should show up near the surface of the water. If it doesn’t, cast the line again, but into deeper water.
- Wait until bubbles start showing around the fishing float/bobber, making a splashing sound. This indicates a fish is testing your bait, but NOT hooked. DO NOT REEL IN YET! YOU WILL NOT CATCH ANYTHING IF YOU REEL IN AT THIS TIME!
- Wait until your fishing rod is pulled, changing the angle of the fishing rod. REEL IN the fish by left-clicking. It should appear in your inventory as a Raw type of fish.
- Cook the fish at a Campfire, because eating Raw fish will lower your immunity to disease.
That is how you catch fish in Unturned.
