Capcom is saying that Dark Void Zero is out for the iPhone in this press release I have right here. I was going to download it and check it out to tell you a bit about it, but it's not actually up on the App Store yet. I'm sure it'll be worth my $2.99 when it finally drops. I think it's the DSi version, just modified with touchscreen controls. Capcom says it in a...different way in this release.
The 8-bit-ish reworking of the world of console game Dark Void is also coming to the PC for $5. Both versions have achievements (PC via Steam, iPhone via OpenFeint). Both also share something else with the console game: a score by Battlestar Galactica composer Bear McCreary. When I saw this game earlier this year, Capcom told me that Bear (awesome name!) reworked his tunes into chiptunes for this game. Neato!
