In Game Over, Upgrade and Gwen ended up in the game. They did not have much trouble fighting the robots, and Ben even stated that they were very "level 1". Upgrade easily controlled the robots and defeated them, earning 500 points for each Robo-Sumo destroyed. A little later, the Robo-Sumo boss emerged and made Ben lose a life. Gwen defeated the Robo-Sumo boss and earned a 100,000 point bonus, and the two eventually found the dojo and crossed the level.
In the second level, Ben and Gwen confronted more Robo-Sumos, only of another kind, and that's when Ben ended up finding the icon of Four Arms.
