Trolls vs Vikings has revolved into version 2.0.2 with a massive update known as Valhalla that brings huge new contents and great improvements.
First of all, this Valhalla update adds more than one hundred new fun levels to Trolls vs Vikings, challenging players to take down new enemies and conquer a new region. Then, with this free content patch comes a few adjustments in both mechanics and graphics. The difficulty tiers of both Normal and Hard in many levels are tweaked and dialed down a little bit to provide a smoother experience. Also, the world map is revamped with new graphics, icons and loading screen, while new texts and tips and the like are inserted into the game. And the soundtracks are updated as well; so is the socialization, which becomes easier for players to play and share with friends.
New elements and improvements aside, another big change is the price drop of most in-game items, which is frequently asked by players and thusly answered by the developers.
Trolls vs Vikings is available for free download on the App Store.
