Good price, cheaper than Base (for the time being) on both formats. Amazon are currently showing no stock on Xbox One and PS4 is 2-5 weeks wait.
Use code EASTER (credit to @alphamike for the heads up).

A Way Out is a couch or online co-op only game where you play the role of one of two prisoners in a daring escape from a maximum-security penitentiary. What begins as a thrilling escape quickly turns into an emotional adventure unlike anything seen & played before. A Way Out is a two-player experience. Each player controls one of the main character, working together to escape the prison and continue beyond into each character's lives. It is a game that explores the notion of trust, betrayal and facing up to the consequences of your decisions.

*edit* Certainly seems you can't do PS4/XBOX, so I'm gonna assume any combo of cross platform isn't possible.
