Clear Sky[]

Inventory icon.

Inventory icon.
Flash drives in Clear Sky are a more significant part of the gameplay, compared to the first game. They are used to store upgrade information, and technicians that are capable of upgrading the player's equipment offer a reward for those that are delivered to them. Flash drives are obtained from stashes (whose locations can be bought from certain characters), or as rewards for certain missions. Note that if the player fails or cancels one of these missions, they may render a flash drive impossible to acquire.
Each flash drive contains data about only one specific upgrade, and since each technician in Clear Sky has a narrow area of expertise, they will only request flash drives that they can work with.
