The contract, published by the
LA Times and made public as part of the lawsuit between Activision and Call of Duty creators Jason West and Vince Zampella, reveals Bungie has signed up to make four "sci-fantasy, action shooter games" in the Destiny universe every other year from autumn 2013 to 2019.
On top of that, Bungie will make four downloadable expansion packs codenamed Comet every other year from autumn 2014 up to 2020.
The first Destiny is for the Xbox 360 and the next Xbox, called the Xbox 720 in the document. It will be sold in shops, but will be boosted by DLC, subscriptions and micro-transactions. Activision and Bungie are considering a PlayStation 3 port for release in 2014.
Subsequent Destiny games will be made for Xbox consoles, PlayStation 4 and PC, if they are considered feasible.
