Your name is John White, an scientist who escaped from black mesa in a car. After 1 week of driving, you find yourself with almost no fuel, you enter in a warehouse but you doesn't find anything useful. In total desperation you use a crowbar to break a vent, only to find the beginning of your journey...
This is the last pic from map b3. This mod will not have any updates soon, the problem?. I broke my right wrist (shit, it hurt).
Oh I hope you will feel better very soon..
As for the map shot it looks kinda nice.. Perhaps add some signs or text to the walls and add some more geometry to them too you're fit again.
Not sure about the sandbags there are they covering the inside or outside of that corridor. If it's the outside I guess it makes sense. Otherwise not so much in that angular but well the player wont know it anyway. Perhaps place a military radio on a smaller army grate next to the sandbags against the wall to make it look like a former small guard post.
Also perhaps some dead bodies? Or you just didn't get to the part yet of filling it with npcs idk. :P
Yes. I still did not put any entities, i prefer to make the map first.
