Can smb write hear about plot of this story. I didn`t understand why we launch a rocket

Hey there, I'm stuck in the room where you go up the stairs to the right into a room with a button to vent the chamber and a valve that I think is supposed to do something. How can I progress from here?

Hi I will translate this great mod completely into German if you want. Let me know, kind regards. Mr. Duke

would love if i worked

The install requests are so weird that I feel I am something that didn't agree with me. I did download the game and it ready to install but the text still says i need base game, which is on the HF2 engine, does the dev now requires ep 1 and 2 to run the game now?...
