Sony Computer Entertainment America (SCEA) has confirmed that it will be releasing the expansion for PixelJunk Monsters, Encore, in North America some time in April 2008.
The expansion will feature 15 new stages to play through, new visuals including weather effects, as well as various tweaks to gameplay elements.
Sony has yet to announce when Encore will hit European territories.
Developed by Q-Games, PixelJunk Monsters has players defending a castle from waves of enemy attacks; the object of the game is to place various defence mechanisms around the structure, each one sporting its own particular ability, ranging from rapid fire, air defence and more, in an effort to quell the invading army.
Stay tuned for more information on the release of Encore as it breaks.
