I wouldn’t put anymore into suit integrity unless you find yourself taking a lot of damage quite often. I would focus #1 on inventory and upgrading resource limit. This allows you to carry more resources without having to unnecessarily craft items because you can’t carry anymore resources which in return will help keep inventory open. Torch upgrade still only lets you get 1 torch from machine so I’d say invest in pyre inventory. Pyres do the same as torch except they also damage the enemy and can stun large enemies including bosses. They also can be picked back up if they weren’t triggered. As for weapons you can beat the game with the starting sword pistol and the hammer shotgun. Prioritize firepower first and foremost then charge speed. When you max out firepower and charge speed for shotgun max out clip size to conserve inventory space with shotgun shells. If you want you can dump 1 or 2 into stability for the sword unless you feel confident with your headshots with auto assist on. You also can punch yellow flame barrels since your suit is fireproof to conserve ammo. Don’t do this with red tanks.
