Don't miss new part of the legendary game familiar to millions of users from all over the world from the childhood!

The war to save the Earth is on a full scale, severe fights are all over the planet surface.
Scientists are studying the imminent danger, but the volume of information about the monsters that we have is awfully small.
Nobody knows where did they come from, whether they have leaders and how to stop the invasion...

The Headquarters have received SOS call from small human settlement situated in the European part of the planet.
Right after the communication with the city was lost...
Here the adventures begin!

Head to the Lost City, save the citizens alive and find the source of invasion.
The information received may have decisive influence on war results.
The fate of Humanity depends on You again!

What's new:

- new missions in the Lost City. Attention! Don't miss enormous enemy in the last mission!
- gaming in open area. Various locations including forest, village, severe fights on roads and in the city.
- realistic weather conditions, dynamic change of day and night.
- new kinds of monsters, they can fly now!
- new gadget - monster radar! Plan your tactics following monsters on the map.

I love this game

I really liked it.

Ayon Abdullah

I really liked it. I really did. But there can be some improvements in the game. Sometimes while fighting a huge wave of monsters, the soldier gets stuck somewhere
like in the trees or doors of cars etc. We can see that from the first mission to almost every mission. This sometimes causes great problems to us. We might loose vital health or life or loose our Drone and Armor. It may also activate our medical set when we don't want it. So, please improve that. But this game is great overall. Just improve that part please. Thank You Sigma Team.
