Frozenbyte unveils "Goblin Menace" expansion for Trine 2, coming to PC, Mac, Linux and Wii U.

Frozenbyte's visually lush action-adventure game Trine 2 will expand with the Goblin Menace add-on campaign this fall, the company announced at Gamescom. Goblin Menace's six unique levels will also be included in the Wii U release, Trine 2: Director's Cut, due this holiday season.

Trine 2: Goblin Menace will add new skills to the game, which will then be playable in the original campaign. The expansion is currently playable at Valve's booth at Gamescom.

Release date, additional platforms, and pricing are expected later. For now, see what Trine 2: Goblin Menace has to offer graphically in a new trailer and new screenshots.
