The best weapon depends on route state: melee is safer when you need blocking and close control; guns are stronger when ammo and sight lines are reliable; Katana is a high-interest melee target when its route is verified.
For beginners, a “best�?weapon is not just high damage. It is the weapon you can actually obtain, support with healing, and use near a known exit.
Use the Tier List after checking whether your route has food, water, ammo, and a backup weapon.
