First played on PS3 when is new.
Gameplay wise is Beat'em up. Easy to try but hard to master the speed of the game. The four (DLCs Players included) run, jump, dodge, and of course beat them up. the leveling system is simple with the max lv. of 16. Level farming is seem easy by farming. to me at least by just play a certain level. The game has some difficulty selection from easy to Double Dragon as Hardcore. Sure. You can continue to progress as you wish. once you get good at it. your on your way to excellence.
The Plot is to me simple as it sounds. Y'know Beat the 7 exes. dethrone G-Man Graves. All Players has its own ending. (If you wanna know the lore)
The Soundtrack is one of my favorites. Anamanaguchi Nail some of the jammin; track. I'm all for 180 bpm track though. And the Chiptunes are a bless to listen to.
