Frozenbyte is working on the large-scale expansion for Trine 2, targeting sometime before summer. You may have noticed it getting warmer outside, so that deadline is approaching fast; but to hold you over in the meantime, the developer has released a video showing off the concept art for the upcoming DLC.

In the short video, concept artist Juhani Jokinen shows the steps of making a finished piece of concept art that will be used in creating the new areas. The expansion promises six stages, with new enemies and a new story. Plus, each of the heroes will get new abilities that they can take with them back into the main adventure. Check out the concept art trailer for some insights on the development process.
