Ok guys, here's solution:

Put in your Internet browser this steam://nav/console and press Enter.
You open console at Steam.

Now at Steam Console copy this:
download_depot 2328450 2328451 2280164651803198156 and press Enter.

After Steam download depot, go and copy all you find here:
C:\Program Files (x86)\Steam\steamapps\content\app_2328450\depot_2328451

Now go where your original game is installed and deleted all there and put all what you copy at Steam depot.

That's it :) Go launch the game like you originally launched and play it for 30 minutes to get two broken achievements:

Fallen
You've felt what it's like to fall into the hands of an alien.


Survivor
You met them and survived.



Good luck :)
