Shadowgrounds developer Frozenbyte and French publisher Nobilis have revealed an intriguing PSN and PC game called Trine.
Due in the second quarter of 2009, the idea is to hot-swap between three classes in order to reach the end of the level.
The first video, which sits on the Trine website, shows a Wizard character summoning platforms and physical objects in order to solve puzzles and bridge gaps.
Then there's a Thief who fires her arrows from afar to deal with baddies, and uses a grappling rope to hook onto platforms and swing across large chasms.
Finally, a Warrior character is at hand to use his big hammer to smash the living - or not-so-living - daylights out of any skeletons or fantasy baddies silly enough to get in the way.
Trine looks rather nice, too - but then we like robes and wizards' hats and things. The full website should launch as this year turns into next.
