This entry corresponds to The Gates of Zendocon, one of the Lynx's launch cartridges in 1989, developed by Epyx and published by Atari Corporation: a side-scrolling shooter in which the player travels through seven floating worlds, each divided into zones with its own boss, rescuing captive characters along the way. The ZZZ-UNK prefix appearing in this entry's name is a cataloguing artifact from the original source, not part of the game's actual title. Beyond that naming curiosity, it's one of the best-regarded shooters in the Lynx's launch catalog, with varied level design that made good use of the handheld's sprite-scaling capability.
