Trine is a physics-based fantasy platform adventure that looks really rather good. The press blurb explains the main concept: "Trine is a fantasy action game where the player can create and use physics-based objects to beat hazardous puzzles and threatening enemies. Set in a 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…"
Anyway, that physics action makes it a rather splendid puzzler - a kind of Crayon Physics meets Prince Of Persia - so take a look at the trailer after the jump for elucidation. The game is due to hit in Q2 next year.
