I just finished this amazing game, and even greatly enjoyed the co-op missions. Now I have even more reason to play. The High Tides DLC co-op pack, available for free today on the PSN!
“The co-op story is far from over. The High Tides DLC contains two new story chapters with four to five missions each and four character skins for Mikhail, Callum, Tisha and Leonard. Hoyt’s privateers have ambushed the four survivors and taken them hostage. It’s up to you and your friends to escape an underground prison and find a way off this island of insanity.”
