Ghost 1.0 : Support Mission Skin

The purpose of this DLC is to support the developer and for the development of Missions Mode, which is available for free.
As thanks, you'll gain access to a new skin for Ghost that can be used in Missions Mode and also, upon completion of all of the missions, in the main campaign.

IMPORTANT: You do NOT need this DLC to have access to "Missions Mode".
