Enjoyed the mood of the game so much. running into a pack of zombies while I was running from another pack was nerve racking lol. I went through the golden door(as everyone probably did lol) obviously did not work out, then I tried to lure the zombies into the golden doors but I guess they were not interested in that.
then I tried to kill myself to wake up from the dream and guess we all know how that turned out lol. then I tried to escape from the holes that zombies were spawned and no luck there either. finally I turned on my zombie killing instincts and killed all the zombies and decided to remain in the facility in peace.
I'm not sure if that was the ending but that was certainly good enough for me.
