Hudson Soft developed Godzilla: Battle Legends on the PC Engine, for Japanese movie studio Toho in 1993. It is an energetic 2D beat ’em up with characters featured from the infamous series of monster films.
In single-player mode you can only play as Godzilla, but in two-player mode you can choose between whoever is unlocked. Which makes for immense (and hilarious) battles between monster rivals.
The game features the following monsters: Anguirus, Rodan, King Ghidorah (Showa, Heisei and “Mecha”), Hedorah (in two different forms), Gigan, Megalon, Mechagodzilla (’74/MK 1, ’75/MK 2 and ’93/Super Mechagodzilla), Super X II, Biollante (two forms: rose & final), and Battra (two forms: Larva and Imago). Unfortunately no Mothra, though, but what there is should be enough to please any Godzilla fan.
