The Spacebase DF-9 Blog has word that Spacebase DF-9 is now available, along with word on the version 1.0 that represents the official release of Double Fine Productions' space strategy game for Windows, OS X, and Linux. They also announce they are giving a free copy of Hack ‘n’ Slash to supporters of this game (and vice versa), along with a price change and a bundle offer, all likely a response to complaints about changing plans for the game which Tim Schafer subsequently addressed. Here's word:

The 1.0 release also sees the game’s price drop to the science-fictionally appropriate price of $20.01 US. In addition we’re introducing a new bundle of our two community-voted Amnesia Fortnight turned Indie Funded projects, Spacebase and Hack ‘n’ Slash, for $24.99. As a bonus for the customers who have supported us thus far, anyone who already owns the game gets a free copy of Hack ‘n’ Slash, and anyone who owns Hack ‘n’ Slash gets a free copy of Spacebase.

As we’ve done with all our alpha releases, we’ll roll out minor updates in the next few days or weeks to fix any issues that come up.

Thank you so much for your support and patience for the past year. We’ve learned a lot and are proud of what we managed to accomplish, and it’s all thanks to your support. And now, we must return to our home planet… hope to see you on worlds beyond!
