Trine 2

Trine 2 is an upcoming side-scrolling action platform and puzzle video game, pretty much like its predecessor. Trine 2 will allow three players to play the  roles of wizard, thief, and knight in a  cooperative mode just like the last game.

The game is actually beautiful as you can see from the trailer.  I played the first one and I enjoyed it very much and I expect even more from the second one.

You can see bellow the release date and system requirements.
