Deep Freeze is Megaquarium's most ambitious expansion to date, combining the Earth's deep ocean and polar regions into one expansion that's bursting at the seams!

The Abyssal Zone

At a depth of 3000-6000 meters, known as the abyssal zone, some of the world's most weird and wonderful creatures dwell. By recreating these conditions in high-tech abyssal tanks, you can bring these critters to the surface!

From the alien Peacock Squid to crowd pleasers like the Anglerfish and Goblin Shark, you never know what is lurking in the deep.

Polar Party

In the polar domes, seabirds like the Atlantic Puffin and Snow Petrel wheel overhead, while Adélie Penguins and Crabeater Seals lounge on ice floes.

These specialized, enclosed tanks need to be supported by racks of compressors and air conditioners to keep them cold!

Freezing point

An array of fish, specially adapted to freezing temperatures add new variety to your coldwater displays. However, your chillers will be working overtime to keep them superchilled; just one of many demanding new care requirements you'll need to master.

Intelligent animals require interactive decorations to enrich their habitats and the most delicate species require regular observation. Will your staff management skills meet the strain, or buckle under the stress?

Breeding credentials

Establish yourself as a master breeder as you rear a wide selection of baby birds and mammals. Each species has its own distinct breeding requirements, can you breed them all?

Accessories, Posters, Gift Shop and more!

Unlock new accessories to equip your staff with powerful bonuses. Meanwhile, precisely placed posters will net you points and a snuggly addition to the gift shop will swell your coffers.

Create the ice palace of your dreams with frost-themed paint and decorations. Plus, brand new substrates allow you to put a creative stamp on tanks like never before.
