This Add on is available on Xbox Live at a price of 800 Microsoft Points or completely free if you are a season pass holder. So If you own Gears of War 3 Season Pass make sure not to purchase this from the Market Place. SEASON PASS owners should only access this update from the in-game store to avoid a duplicate charge. If you are already done with existing maps on Gears of War 3 then Fenix Rising has got five new multiplayer map packs which takes you to complete different level as you will need to use altogether different tactics.
