Panther is a Commodore 64 game designed and implemented by Peter Adams and published by Mastertronic in 1986. An Atari 8-bit family version followed in 1987, then a ZX Spectrum port in 1989. The player pilots a strange-looking aircraft, fighting off hordes of invading flying saucers and rescuing people by landing the craft and waiting for them to board. The game uses a diagonally scrolling isometric view, much like Zaxxon and Blue Max, using shadows to show the height of flying objects. Adams previously worked ports of both of those games.
The Commodore 64 disk packaged Panther with L.A. SWAT, another Mastertronic game. The A-side of the disk contained the two programs for the C64/128, while the B-side contained Atari 8-bit family versions.
