Loneliness addon

Hello!
This is my first map loneliness. It is inspired by fn unfinished fim by Andrey Tarkovsky "Septentia" from 1976 and by mapping experiment.
There was a moment when director forced a viewer to watch at a meditating alien in a coridor for 45 minutes.
So in this map you have to walk in the straight line for 31 minute without sprinting.
1 enemy
1 exit
nothing else
To play extract Loneliness.pk4 file into base directory of your DOOM 3 game. Then bring console by pressing ctrl+alt+~
or just ~ if it is set in your options.
Then type g_skill for skill level
0 - recruit
1 marine
2 veteran
3 nightmare
Then type map loneliness
