Spectar

Spectar is a maze shooter released in arcades by Exidy as a sequel to Targ.

It adds blockades to the maze, breaking up the regular grid.

The center of the maze has a number of twinkling stars that the player can pick up.

The enemies change shape every round (and are worth more points for shooting as the levels increase).

There were a number of bootlegged versions of Spectar released by Exidy rivals which had identical ROMs except for the title screen game names: Panzer and Phantom (released by Proel), Phantomas (Jeutel), and Rallys (Novar).
