The whole thing takes place within an enclosed dome set in space. You will battle 7 different enemies, each with an individually tweaked AI. In addition to delivering fun, knuckle-blistering gameplay, CyberDome includes a very nice 8-level training mission to let you learn basic concepts of the game. It also has a very nice auto-targeting feature that makes the gameplay much quicker and more fluid – as all arcade shooters should be. Formerly published as shareware by MicroLeague, the game has been released into the public domain by the designer himself. If you like a fun arcade shooter similar to Tempest 2000 but with more complex graphics, give CyberDome a try. It's fast, smooth, and looks great on a wide range of 3D cards. Highly recommended!
