Hello dear players!
MISSION MODE
Version 1.1 is Live! Includes the "Mission Mode", a new extra content that includes 12 independent short missions to be done in around 5 to 15 minutes.
Each mission has 3 achievements. One to complete the mission and two more to be achieved by doing something special in that particular mission.
By default missions will be locked. This is done in order to prevent spoils. As you progress in the main campaign, your'll find icons of missions that will unlock them.
If you already finished the game, then all missions will be available by default (obviously there is nothing to spoil if you already finished it).
Last, but not least, if you already started a game and don't want to search icons, feel free to use this map to locate them:
This new content is free and is included in the game. No DLC is needed.
MISSION SKIN
In case you like the new extra content and you want to help a bit, there is a DLC called "Ghost 1.0 - Mission Skin" you can purchase.
It totally optional, and as thanks, you'll gain access to a new skin for Ghost (visual change, no special abilities).
http://store.steampowered.com/app/614080/This new Skin will appear directly in the "mission mode" and, if you complete all 12 missions (secondary achievements not needed), then this skin will also be available in the main campaign, so you can select it in 3D printers.
