well, I got past that point, but now I have some problems (again)
1. How can I change my weapon? I found a weapon lying on a table, but iÍ can't pick it up, when I select it with "s" and press "u" (use), I just stays there, so I don't know how to pick it up nor how to change weapons.
2. Since there are no videos in the game, I don't know what I have to do...
