This game has music by the Guilty Gear composer Daisuke Ishiwatari and it ROCKS. The game is tough as nails but you are able to grind levels to afford upgrades. Playing through levels with a maxed out character feels powerful. You are able to do so many acrobatics and deflects- Each playable character has a unique quirk/playstyle that makes doing doing the grind all over again to see their full potential really enticing.
Playing this game with a friend online is so fun, you'll get tense moments where everyone is out of lives and it's up to the remaining player to clutch it out. This is the best Contra ever made.
