Effective resource management is crucial, especially on higher difficulties. Always scavenge every area for health, armor, and ammo. Don't waste heavy weapon ammo on standard enemies; save it for armored foes and bosses. Overcharge your health and armor whenever possible before entering a new area. If you're low on a specific ammo type, switch to a different weapon or resort to stealth takedowns to conserve resources. Remember that some perks can increase ammo drops or health regeneration, so invest in them if you struggle with resources.
