Overshield is an upgrade from the Slush Invaders: Game that allows Stickwart to take two hits before retreating. Note this means INDIVIDUAL hits. The effects of the Drab's bullet stream will cause Stickwart to be sent back.
Trivia
- Rarely, Stickwart may take three hits instead of just two, which is a handy glitch in allowing the player to have Stickwart open fire continuously before retreating.
