KILO (₭) is an in-game currency and the lifeblood of Department 77. It's currently denominated as aKILO (alpha KILO) because it's not yet an on-chain token. aKILO is used for everything, from buying items at vendors to ordering custom shop droids.
You can get aKILO from doing missions, selling loot or trading materials. Once you have enough aKILO you can use it in the Custom Shop to design your own custom droid that is then minted and airdropped to your wallet.
