To meet his blind date, B.O.B. the android lad must battle through 50 side-scrolling levels across three perilous planets. Each one offers unique landscapes, such as Goth’s carapace caverns, Anciena’s evil temples, and Ultraworld’s gelatinous blobs, and all are riddled with enemies, including robots, flying jellyfish, and excreting insects. These quickly drain B.O.B.’s life meter, so finding health-replenishing wrenches is key to survival.
