Contingency Contract #0 – Operation Barrenland, often simply known as Contingency Contract #0 (CC0) or Contingency Contract Barrenland (C.C. Barrenland), is the second season of the namesake seasonal event in Arknights.
C.C Barrenland introduces new mechanics that would become the standard of future C.C. events such as Training Grounds, Ratings, Permanent and Special Trade Centers, and Support Unit Highest Risk, which is the reason why C.C. Barrenland is designated as "Season #0" despite technically being the second season of C.C..
With the release of C.C. Pyrolysis as the first iteration of C.C. Battleplans, C.C. Barrenland becomes the first iteration of C.C. Operations which spans up until and including C.C. Base Point.
