Robby Roto

Robby Roto (referred to as The Adventures of Robby Roto on the flyer and marquee, and Roto to the Rescue on the title screen), is an arcade game, released by Bally Midway in 1981; it runs on that company's Astrocade hardware, and was designed by Jay (now Jamie) Fenton. The player must use a 4-way joystick to take up controls for the eponymous "Robby Roto" (who looks somewhat like a red version of Namco's Pac-Man with legs and a mining helmet) as he ventures into the home tunnels of "Voltar", an evil monster who has invaded the Earth and was created 27 years before The League of Super Evil was even thought of - and his goal is to save the captured hostages (sad yellow faces) by touching them and causing them to follow behind him for the rest of the stage, as well as recover the stolen treasures. But Voltar's servants, the "Sinister Spiders", the "Wicked Troll" and the "Jawbones" will not make this an easy task for Robby; if they catch him he shall lose a life. Robby can, however, use the "Magic" button (once per stage) to make him and all hostages following behind him invisible and invulnerable for a few seconds - and he will also be granted an extra life after every third round. Once he saves all the hostages, he must find the key to open the gate and escape from the tunnels.
