Trine is a beautiful fantasy action platformer with a fairytale-like atmosphere, following the journey of three heroes - a Wizard, a Knight and a Thief - in a quest to save the kingdom from evil. The gameplay is based on fully interactive physics - each character's different abilities and tactics can be used to invent new ways to battle an army of undead and overcome obstacles, and restore the balance of the world.
Trine was fun, one of the few newer games that I actually completed =P. I haven't tried the co-op splitscreen mode yet, but I will during my second playthrough. It's a really beautiful platform game where you will solve different types of puzzles with different character, who has different abilities. There's some bonuses along the way that I like, find hidden items for example, gives you another reason to replay. Good Game!
