"One of the great things about the multiplayer and the co-op is that it gives us great opportunities to expand the experience for players with downloadable content, unlockables, things like that. Which of course you don't really do with the single-player game that much. We tried to pack a lot of value into the first game in terms of unlockables, but with that online component the game can kind of keep growing, especially based on players' feedback too."

Good to see that the game is going to remain fresh with DLC, mainly for the Multiplayer feature of the game!
