Frozenbyte's upcoming action-puzzle game Trine had a couple of news announcements this week; one was that it found a retail game publisher in Southpeak Games and the other being the release of a playable demo. Now comes word that Trine can be pre-ordered via Steam with a special bonus to go with the purchase.

If you put down your well earned $30 to buy the game you can download and play Frozenbyte's first game Shadowgrounds immediately for free. The $9.99 title is still a rather entertaining and old fashioned top down third person sci-fi shooter but far different than the fantasy action-puzzle game that Trine is going to be when it's released next month.
