Chiong Anh, the Product Manager for UFO Interactive, in a recent podcast announced the domestic release of Raiden IV. It seems it has yet to be decided on whether the game will be a retail release or will be downloadable via the XBLA (Xbox Live Arcade).

So what is this Raiden that we've been talking about? It's a top down scroller that has you fighting over different terrain in your spaceship aptly named Raiden Supersonic Attack Fighter. As you scroll through the different stages, enemies will constantly attack you trying to bring down "Earth's last hope" (That's you!). To help you along the way, you can upgrade your ship with powerups and new weapons.

Raiden IV should be released some time soon, so watch out for it. More news and updates as they happen.
