Often there were titles that had completely different US releases, such as Bionic Commando and Afterburner. Some were just NTSC fixed versions of the UK releases, such as Salamander.
Ajax (or A-Jax) was another title planned for release by Konami in the US, and was advertised in magazines in 1990. It was the world-wide name for Konami’s Typhoon, which Imagine/Ocean had converted to various platforms back in 1988. However, the US version of the game never surfaced at all (or at least hasn’t been seen).
What isn’t clear at this point in time is whether the game was an entirely new development done by a different team, or an NTSC conversion of Typhoon.
We hope to learn more soon, but if you know anything or maybe even have a copy – please get in touch!
