Hi-Fi RUSH

Fairly early on in Hi-Fi Rush, Peppermint will come to Chai with a new invention: the chip board. The chip system allows Chai to equip various chips that enhance your gameplay. These can be things like giving you an invincibility window after a directional parry, getting health drops after a parry, improving Peppermint’s cooldown, and so on. In order to increase your chip slots to the maximum amount (which is 5), you’ll need to purchase 4 “Additional Chip Slots” from the Item menu in the store.

The first one will set you back 20,000 Gears, the second one will set you back 40,000 Gears, the third one will set you back 65,000 Gears, and the last one will cost you a whopping 100,000 Gears. It sounds like a lot, but once you’ve run through the game a few times, it won’t be. Once you’ve unlocked the last one, the achievement will pop.
