Immersion (co-developer of Monster Madness) today announced their new Xbox 360-game: Cellfactor. In this tactical FPS, you're going to kick some ass in a fortress in the Mediterranean sea. It seems to be some kind of mix of Riddick, Ghost Recon and.. well, Final Fantasy, as you this time seem to be able to upgrade your character in many ways. The release? Autumn 2007. Images from a demonstration inside, together with some artworks.
