Nice

Fixed the texture.

I will fix the missing texture and the room is supposed to be a tunnel, the zombies broke in through there.

Very well put together. Realistic looking and fun to play - nice and compact. Missing texture right at the very end on the final door you weld. Also the large dark room on the right of first door could use some props so it doesn't look like an empty void

Overall, if this is your first map, it's a work of art.
