The depths of space are cold and lifeless, but at the center of this asteroid your Dupes are preparing to feel the heat with the Thermal Upgrade!

Key Features:

New Temperature Mechanics: Building meltdowns, burst pipes, spoiled food and temperature-based diseases all await to foil your plans for survival.
New Biome: Venture into the Ice Biome and obtain valuable resources like Ice, Snow and Wolframite, or take advantage of the chilly atmosphere to cool your colony off.
New Outfits: Build your own aquatic farm and grow the resources to weave protective and stylish outfits for your Dupes.
And more: New plants, buildings, resource bonuses, balances changes, bug fixes and more!
