The Team17 Softography Says...
"After the vile sorceror, Hexaa, had tortured your beloved partner to near death, you awake the magic of your grandfather's talisman to summon the forces of light to help you defeat the sorceror.
Featuring 5 fantastic worlds with simultaneous two player action!"
Dream17 says...
This Project-X-alike was published by Team17 in the UK but was developed by Kaiko and shares a couple of similarities with Team17's own shoot 'em up - perhaps coincidentally, Apidya's original, full-price release (published by Play Byte) came at the same time Team17 released Project-X.
Perhaps unlike Project-X/em>, it's actually possible to complete Apidya without needing to ask your grandchildren to finish your game should you die at the controller aged 97. However it would be more accurate to say that Apidya is an imitation of the Gradius series produced by Konami.
Great Game
