Well I can tell you it's a definite purchase. Probably imo the best fighter on the 3DS. The graphics are lush and amazing, the fighting system is top notch and the modes offered give it a lot of replay value.
What modes are offered in the game?
Well there is Arcade mode which is a standard for every fighter, Chronicle mode which explains the DoA story of the last 4 games in one go which makes it kinda confusing but not too bad it also serves as a
tutorial kinda on the controls, Free fight which is basically a mode where you make your own fight with your own rules, Online, Survival mode where you take on a set number of enemies and try to defeat them the more you defeat the harder it gets, Tag Team mode where you fight with a tag partner in set challenges, and practice mode.
