[Game idea "chaos mission difficulty"]

In chaos mission difficulty, enemies all have shields and jump around like tenno. They're also each equipped with a variety of biocoded mods which cannot be equipped by tenno. You collect biocoded mods and break them down to receive endo and have a small chance of receiving a chaos core depending on the rarity of the biocoded mod. Chaos cores are used to increase the maximum number of upgrades of mods. You need a LOT of endo and a certain amount of chaos cores depending on the rarity of the mod and the amount of times you've already used chaos cores to limit break the item. There is a limit to how many times you can limit break a mod and actually upgrading your gear to the newly unlocked limit break will require additional endo and maybe chaos cores too.
