2K Games announces a Season Pass program for Borderlands 2, which will allow gamers to secure four upcoming add-on campaigns for Gearbox Software's upcoming FPS/ARPG sequel for a one-time advance payment. They do not provide exact details on what the add-ons will offer, but say they will all be released by June 2013, and the season pass will reduce the cost of the four packs to around USD $30.00 instead of around $10.00 each. Season passes will go on sale when the game is released in North America on September 18th and internationally on September 21st.
