How are you supposed to defeat the house robots in robot mayhem? I make Sg. Bash fall into the pit but I can't seem to get the others in. I hid behind the pit so the house robots couldn't see me so they started attacking each other and then I went round and bashed into Matilder at full speed and she didn't budge! Then she turned round, flipped me over and it wouldn't let me self-right my self. Do you actually get to be the house robots when you complete mayhem? If you do, are they invinsible?
