People are wondering what they should do when they get to a room with turrets...kill urself and move on to door 2 =D
WHAT YOU NEED!!! You need the new "Atomic" map on the home page!
Installing: drop the save file into steam/steamapps/Yourname/garrymod/garrysmod/SAVE
HOW TO PLAY: You will spawn in a fallout3 type bunker.... Go to the door that is marked 0. This will start off your adventure! Follow the red beacon skulls to the gas station. Once there, follow the pattern of beacons that are diffrent colors. =) Adventually, you will spawn once again at this base. Go to the door marked 2 this time, this will finish your adventure! Good Luck!
