The DSiWare version will deliver a cheaper version of the classic game's recent rebirth.
Taito announced the release of Space Invaders Extreme Z on DSiWare in Japan.
The title is actually a port of Space Invaders Extreme 2 minus some of the modes found in the retail release. The DSiWare version only has two modes: time attack and score attack. These modes will have three levels of difficulty: beginner, normal and extreme.
Space Invaders Extreme Z is already available on Japan's DSiWare service for only 500 DSi Points. There is currently no word on a North American or European release.
