The fourth and final game add-on for Dungeon Defenders released a few days ago at a price of 320 MSP. The last installment will take you on a journey to Sky City where you’ll fight tons of enemies above the clouds in quite possibly the most aesthetically pleasing environment to date in the game. This add-on contains two new campaign levels, a new challenge level and a few more enemies including two new bosses.
