It isn't much of a surprise to see that Galaxy on Fire 2, one of the App Store's most notable space adventures, is going to be getting a second in-game add-on pack. Let's face it, the game is excellent and the added content from Valkyrie was more than welcome. FishLabs deciding to follow it up with a second batch of new things was only natural. Thus we have (or will have, really) Supernova.
Supernova is set to pick up right after the events of Valkyrie. Keith is taking it easy at the Deep Science space station, but it's not long before another galactic peril makes itself known. The entire Mido sector suddenly finds itself threatened with annihilation as a supernova "of unknown origin" appears. Keith being Keith, he decides to get involved. The entire adventure is said to last "at least twice as long" as the previous add-on, with promises of 10 hours of gameplay, new mission types, more ships and more story.
Dates and pricing aren't available at the moment, but it's probably safe to assume it'll cost about as much as Valkyrie ($4.99) and will be out sometime in the second quarter of this year. Be sure to keep a look out for release blurbs.
