Zaxxon © 1983 Coleco Industries, Inc.
One of the coolest handheld arcade conversion, Coleco's Zaxxon uses a unique combination of mirrors and 2 different VFD displays to get a 3-D affect. Your ship appears to be flying above the surface of the planet and actually flies over walls and other VFD generated images (not possible with just one VFD display). The planet's surface and ground based enemies are created by one VFD, while you and air-based enemies are created by the VFD reflected off a mirror.
