It seems that Bundle Stars decided to offer a great freebie for everyone who likes RTS titles. Planetary Annihilation is normally sold for around $30, but now you can get it for free at Bundle Stars’ official website.
You do have of course to follow some steps before securing your Steam Key for Planetary Annihilation. Visit their website here, sign up for the newsletter, join the Bundle Stars Steam group, have a look at some ads and then you’re ready to go.
You should try it out now, because there is no word about how long the offer will last. We tried it ourselves and it worked, but it seems that it’s the typical “while (digital) supplies last”, so you should definitely visit their website during the day.
