Combo+ is an upgrade from the Slush Invaders: Game which allows Stick Brian to increase the Combo Counter by 1 each time Brian extends an attack. It costs 15,000 points.
- This upgrade on Stick Brian adds up to the Combo Counter by 1 each time he is activated through his partner.
- It is best to have Stick Brian and his partner attack an enemy if the Combo Counter begins to fade when your available fighters are recharging, so as to keep it still.
- Rarely, Stick Brian may not follow up with his partner, thus causing a risk for the Combo Counter to fade.
- Additionally, Stick Brian may instead follow up with a fighter who he isn't partnered with.
