Gameplay is pretty much the same and still fun to play. Improved graphics and new abilities. New gun element. Hundreds of hours of gameplay even without the DLC. DLC is a lot more challenging than the main story. After the main story you can apply modifiers to make the replay challenging and fun. The modifiers can work for and against you. A lot more difficult to get customizers for your appearance and vehicle if you're looking for a 100% completion.
