[Borderlands 2] How does Salvador accumulate bullets while gunzerking?
gpt
All the weapons get 'digi-structed' out of your space holster, just like the catch-a-ride vehicles. Finding a weapon is just finding a schematic for it. Your 'inventory' size is limited due to your holster's hard drive space. The limited active slots are the ones it's holding in hot RAM at the time.

These things are also restricted by intellectual property laws. There are a lot of shitty pirated designs floating around, on Pandora especially, but the way it's *supposed* to work is you buy a license for guns and ammunitions, and your digistructey thing complies with those regulations. This is more like a copy-protection Software license than a modern concealed-carry license - it's tightly regulated by the companies, and enforced like the wrath of god, not for public safety, but for profit. The arms dealer situation is fucking nuts.

So, having 200 'bullets' is actually just being licensed for 200 shots. If you kill someone and 'loot' their corpse, you're just finding the cryptographic hash for their licensed bullets and adding it to your digistruct account. They're extremely secure digitally, but almost nobody gets a chance to log off their account when they're being shot in the face. Most violent people pack some free apps to make this 'looting' process quick and easy. Any objects (guns, bullets) you might see lying around are super-imposed by your ECHO HUD based on the active code.

What Salvador is doing is getting really angry and mashing the button so hard and so fast that the software glitches and he gets a few extra shots out.
