Frozenbyte has released a new 'making of' video for Trine 2, this time showcasing the upcoming expansion, which will include a six level campaign with all new enemies and skills. The skills will also be playable with the original Trine 2 campaign, giving it more renewed playability. Also included are some small updates and a new difficulty level, for a very reasonable price. All of this in a brand new adventure where our heroes embark on a new journey more menacing than ever.
The expansion is planned to be available in summer 2012.
