Fishing and boats:
Fishing traps should be a thing it would allow players to place traps on lakes and gather fish as raw fish damaged boots and rare items.
Small Boats would allow players to fish for sharks turtles as well as kill whales for a big chunk of animal fat.
Turtles would make great body shields and helments.
Sharks tooth for spiked fists and spears and arrows.
Whales bones animal fat rare items.
Small boats should be upgradeable with shields to avoid sniper fire.
