Real Time with Pause

This is a real-time strategy game, but don’t get too nervous. You can pause the action to take the best strategic and tactical decisions.

In Pause Mode, you can place structures to build, give orders to your army, or consult all of the game’s information.

This game is all about strategy, not player performance or the player’s skill to memorize and quickly execute dozens of key commands. Pause the game and take all the time you need!

Build your Colony

Colony Management includes:

  • Bring Colonists: Build dwellings and acquire food for the colonists. They will come to live and work for the colony.
  • Get Resources: Wood, Stone, Iron, Oil… Collect resources from the environment using various building structures. Upgrade buildings to make them more efficient.
  • Provide Energy: Expand the energy distribution of the colony by placing Tesla Towers. Build mills and power plants to feed the energy needs of the colony.
  • Protect the colony: Build walls, gates, towers, and structures to watch the surroundings. Don’t let the infected take over the colony.

Thousands of Units on Screen

Yes! They are billions! The world is full of infected creatures… they roam, smell and listen. Every one of them has their own AI. Make noise and they will come – kill some of them to access an oil deposit and hundred of them will come to investigate.

We have created our custom engine to handle hordes of thousands of the infected, up to 20,000 units in real time.

Do you think your colony is safe? Wait for the swarms of thousands of infected that are roaming the world. Sometimes your colony is in their path!

Prevent the Infection

If just one of the infected breaks into a building, all the colonists and workers inside will become infected. The infected workers will then run rabid to infect more buildings.

Infections must be eradicated from the beginning, otherwise, it will grow exponentially becoming impossible to contain.

Build walls and command your army to patrol the colony’s surroundings to prevent the infection.

Build an Army

What kind of people would want to combat the infected?

Only the maddest ones. Train and contract mercenaries to protect the colony. They demand their money and food, and you will have to listen to their awful comments, but these tormented heroes will be your best weapon to destroy the infected.

Every unit is unique and has their own skills and personality – discover them!

Beautiful 4K Graphics!

Prepare to enjoy these ultra high definition graphics.

Our artists have created tons of art pieces: Beautiful buildings with their own animations, dozens of units with more than 1,500 frames of animation to get the smoothest movements, and hundreds of environment assets.

And everything with a crazy Steampunk and Victorian style!
