Thanks!
I was looking for something around this price range and it's Double Dragon!
Controls are not totally clear as on screen popups don't cover everything, if you have problems just check any wikipedia/guide
things to keep in mind:
1) some enemies, when dying, drop a cassette. These tapes gives you special abilities: Sosetsitsu, which you need to activate manually and use your thunder shaped power bar that is below energy bar (it slowly builds up) or Stance, which are always on.
You can use one active and one passive at a time, but you can switch any time you want.
From time to time pause to see which one is better to select according to your style.
2) enter the various shops to get new tapes or increase ability level limit (at the beginning is 10)
Taking/buying additional tapes of the same ability increases its level.
3) when playing with a friend remember to high-five, which allows you to get a temporary boost, split energy or give little energy to the other player.
4) when your friend loses all energy, it will stay down for a couple of seconds before losing a life. If you go next to him and press B like a crazy you can pull him up
5) duck/dodge roll does not seem very useful in the first levels, but later on it become important, so learn correct timing from the beginning
6) as in every Double Dragon game, there is no time for sportsmanship. When you play with a friend, attack the same enemy from both sides and, when he/she drops on the ground, continue attacking for additional damage
