Trine

Trine is a physics-based action game where three characters allow clever solutions to challenges created by hazardous puzzles and threatening enemies. The gameplay is based on fully interactive physics – each character's different abilities and tactics can be used to invent new ways to overcome obstacles and save the kingdom.

Trine takes place in a forsaken and ruined kingdom. After enjoying a period of great peace, the king died without leaving an heir, plunging the kingdom into political instability. Taking advantage of the chaos, an undead army suddenly appeared and attacked, forcing the inhabitants to abandon the realm, save for those few souls brave enough to face the perils that had now befallen it.
