Since Ark: Survival Evolved launched just a few months ago it's been a lock among the most-played games on Steam. The team behind it has set a blistering pace, adding crafting options as well as creatures to the prehistoric survival game and accelerating toward a console launch in 2016. Now, they've added two entirely new biomes to the game, dramatically increasing the diversity of the its landscape.
Ark's standard tropical island is now joined by a swamp and a snow region. Creatures from the original landmass have migrated over where appropriate, only to be joined by new ones including a giant Dire Wolves, Megaloceros "Stags" and giant aquatic frogs. The free upgrade is available for Early Access players right now.
