The award-winning indie action-platformer Trine is now available for pre-purchase via Steam.

Set in a fantasy world of great castles and strange machinery, three heroes are bound to a mysterious device called the Trine in a quest to save the kingdom from evil. Create and use physics-based objects to beat hazardous puzzles and threatening enemies. Switch between three characters to utilize each character's different abilities in battling an army of undead and defeat hazardous contraptions.

Grab a couple game controllers and play co-op with up to two of your friends. Explore the world and unlock all the Steam Achievements.

Customers that pre-purchase Trine before release will instantly get a free copy of Shadowgrounds - the debut hit title by the indie developer Frozenbyte. Already own Shadowgrounds? Give your extra copy to a friend.

Trine is slated to release in early July. In the meantime, be sure to check out the Trine demo to get a taste of the beautiful environments and fine-tuned gameplay.
