Quiet Rehabilitation brings a different story of Gordon Freeman being taken prisoner directly to Nova Prospekt. In this alternate route, without meeting Barney, he must find a way to escape from this old facility heavily guarded by Combine forces and surrounded by unusual creatures.
Still reworking my previous public maps before moving further to the underground. I've managed to increase overall playtime of this small level (on the image comparison top-right corner) from 3~ min to 15 min aprox. I'm holding myself to not spoil things up so have this little media of a sewer tunnel below Nova Prospekt.
Merry Christmas in advance! Stay safe :)
Looks great, like what you've done with the lighting.
