All the colonies are on high alert and only the maddest ones dare to fight infected. Roam the population of those bastards with shotguns and build fortified colonies, place structures, power plants, and other various building structures. Watch out for infected workers and build a successful colony. It’s a survival mode in a real-time strategy game!

Gameplay and Mechanics


The game looks beautiful with victorian style art pieces!


It’s a distant future, so – things did not work out as well for humans as you may imagine. You are managing human colonies after a zombie apocalypse that almost wiped all of humanity off the Earth!

Well, now there are only a few of us left, so why wouldn’t we fight for our survival? As the title says – billions of infected creatures quickly execute dozens of our people. Your job is to create such a colony that can fight them off.

Acquire food, upgrade buildings, collect resources, and take care of the oil deposit energy distribution by strategically placing tesla towers. Lands devastated can be taken back by tormented heroes with their own skills! New empire will rise in this crazy steampunk game!

Let’s check out some details then!



Everything depends on the player’s skill!


Or we should say – survival mode is what makes this game so unique. A random world is being created where the events, weather, geography, and zombies are made up on the spot. You have a colony to run and try not to get yourself killed. 

Many have tried, not so many survived in building and managing human colonies while the zombies are attacking the world in massive swarms. Build walls to handle hordes – more buildings mean more security until infected breaks in – then – you are done.


Pause mode can be really useful!


Developers plan to create a sort of challenge. Players will get the same random map and those who survive the longest can be published on a leaderboard like in an old-timey game saloon. It’s an ultra addictive game mode so use it with caution! Or not – your choice!

Relax – You Can Pause Your Inevitable Death!


You can create your own buildings!


As funny as it may seem – yeah, it is a real-time strategy game, after all, with a pause button. What does it mean? Well, it’s not like you can delete some ground under the hordes of zombies at the moment, but you can strategize!

You can choose the best weapon, contract mercenaries, and build mills while billions of infected roam your home. It may not be the easiest way out, but it is satisfying.

Build Your World!


Do not let those basterds roam free! Arm yourself!


Speaking of building – it’s a strategy game, after all. You will need some food and people to live and work for your colony. You can gather resources from the world around you and upgrade everything to have a better security system.

Fortify yourself with gates and towers. You cannot let those zombies grow exponentially, though, so remember to…

Arm Yourself!


Do not let those basterds roam free! Arm yourself!


Exactly! You can sit in a castle all you want, but one day there will be a bulldozer that will crush the basis of your world! Also – zombies like to make awful comments at survivors, so you may want to protect your workers inside from those slurs (heard they call them the “Z” word).

Alive that must struggle, must also fight back – as the saying goes, so arm yourself up to the teeth and run rabid zombies to the ground!
