Finnish developer Frozenbyte now offers a free content update for Shadwen. Titled Escape from the Castle, this is available for the stealth game on Windows, OS X, and Linux. As may be inferred from the title, this reverses the original campaign's infiltration goal. The game is also currently on sale for half-off on GOG.com, Humble Store, and Steam. Here's more:

The levels are reverse and remade versions of the ones in the orignal campaign - the objective now is to escape from the King's Castle!

The difficulty curve in the new content has been increased and players are encouraged to search for hidden treasure maps scattered around the levels!

The update also includes numerous bug fixes and some tweaks to the game's AI.
