Pitfall II: Lost Caverns is a platform game originally released for the Atari 2600 by Activision in 1984. It is the sequel to Pitfall! (1982). Both games were designed and programmed by David Crane and star jungle explorer Pitfall Harry. Pitfall II adds a much larger world with vertical scrolling, swimmable rivers with deadly eels, music, and balloons for floating between locations. Published after the video game crash of 1983 when interest in the 2600 was waning, Pitfall II was one of the last major releases for the console and one of the most technically impressive. The cartridge contains a custom "Display Processor Chip," designed by Crane, for improved visuals and four-channel music instead of the two the system is normally capable of. Pitfall II was ported to the Atari 5200, ColecoVision, TRS-80 Color Computer, Apple II, Atari 8-bit family, MSX, Commodore 64, and the IBM PCjr (as a cartridge). In 1985, Sega released an arcade remake of Pitfall II with a new visual style and gameplay elements from both the original and sequel. It was ported to the SG-1000 console in Japan. The game's plot was loosely remade into Super Pitfall for the Famicom/NES. Gameplay In Pitfall!, Pitfall Harry avoids crocodiles, scorpions, cobras, bats and quicksand across a series of horizontal screens. Lost Caverns dramatically expands the scope of the environment, as Harry descends into a deep, vertically scrolling underground. Unlike the first game, Harry has unlimited time and lives, making it impossible to die or lose. When Harry touches a dangerous creature, he loses points as he moves back to the last continue point (marked with a red cross) he touched along his journey. Pitfall II has 27 horizontal levels. These levels span eight screens in width but are not openly accessible all the way across; some portions are blocked by cave walls that force Harry to travel through other areas in order to progress. Quicksand and tar pits are replaced by rivers and chasms. Balloons let Harry ascend to new areas. Two characters debut in Lost Caverns: Quickclaw, Harry's cowardly pet mountain lion, and Rhonda, his adventure-seeking niece. Both characters were created for the Saturday Supercade cartoon based on Pitfall! a year before this game was released. Upon collecting Rhonda, Quickclaw, and a diamond ring, the game ends. Optional items can be collected for points. The maximum possible score is 199,000. Musical cues act as subtle rewards
