it seems you forgot to add a price to the game for the EU, so it is not possible to buy this game from within the EU.

How to solve this achievement, this achievement only 0.4% unlock

How to get it? Help, please. I tried to live a long time, at stage 4 I lived 30-60 seconds. I also tried to kill as many as I can, and I was able to kill two clusters at stage 4. Can someone tell me what exactly is needed.
