Cannon: Breakerblast

Items: Rich Cat, Cat CPU

Notes: "Research" Effect UP Combos recommended. Don't use Cat CPU if you use Combos.

First spawn some meatshields and some attackers to kill the first two Mistress Celeboodles for money. Then turn on the Cat CPU. Be aware that when the Cat Cannon is ready for the second time, turn off the Cat CPU and continue to spam the cats. When the Zir Zeal is trying to burrow, fire the Cannon to cancel his burrow, or else you may lose.


  • Demon Eraser is a Merciless stage in BCJP, but is only Insane in BCEN.
  • Prior to Version 13.0, the enemy base had 800,000 HP instead of 2,500,000.
