Button Punch+

Button Punch+ is an upgrade from the Slush Invaders: Game which lets Stick James's punch recharge all allies on the team. This is represented with a red button icon on the other fighters' icon box. You will receive bonus points if you recharge 2 or more fighters. It costs 40,000 points.

Trivia

 * The upgrade is pretty handy against a handful of enemies, most specifically against the Blue Base level.
