Wipeout

Wipeout is the upgrade from the Slush Invaders: Game that allows Stagar's snowboard to stay and hurt enemies after he has been damaged to send damage.

Trivia

 * Though a risk, it is mostly recommended that players allow Stagar to be hit by an enemy, preferably enemies that attack close range, for his snowboard to hit anyone. This is basically up to the player if they want this upgrade to have full effect.
