The Leviathan-class Ice Worm is ready to stalk you across the Arctic Spires as you explore the vast biome. Make use of your Thumper to distract the creature and escape quickly to avoid an aggressive encounter!

Story Updates

Due to continued community feedback, we’ve been working hard on bringing you a higher stakes introduction, as well as fleshing out the mid-game story. This Ice Worm update includes all-new, text-only dialog throughout. Voice overs will be coming in a future update.

Arctic Spires

Lilypad Islands

Don’t worry. This huge Leviathan-class creature can’t get to you from behind its frozen encasing. But just what was Alterra chipping away at the ice to discover…

Pengwing Behaviors
