A player can unlock the skin without the pre-purchase after completing all nine missions of the campaign. Those who pre-purchased Nova Covert Ops received a unique Nova portrait, as well as a Covert Ops ghost skin.
Only the StarCraft II Starter Edition is required to download the missions. Each mission pack will be $7.49 USD, while the pre-purchase option comes to $14.99 USD. Each mission pack can be purchased separately, but only the bundle is available for pre-purchase. A bundle could be pre-ordered that grants the purchaser access to all 9 missions through a single payment.
