Since 2.0 instead of buying consumable items you have consumable item types that can be upgraded and a certain amount of charges with a cooldown. These can be upgraded by finding/ buying health item upgrades and perks
So you don’t have to save them because they will regenerate in 20 seconds and you can’t just spam them in fight like in previous versions
Do you know how good those computers are ? They have shitty reparability, but otherwise they are great value.
