The “retro” Dark Void game Dark Void Zero hits the iPhone and Steam today, and if you think you played the whole game when it was on WiiWare, you are wrong, sir! Not only does the iPhone version use OpenFeint and the Steam version use Steam Achievements to reward you for playing, but players can unlock a secret ending! Who doesn’t love a secret ending? The game should be available now for $2.99 on Apple’s devices and $5 on Steam. However, I don’t currently see it on the app store on my iPhone.
