Once you get outside, follow your map marker to the first CCTV junction box. Scan it and then make your way to the next marker.
Manhole's serve as the games fast travel points. They stay with you even if you die and use another survivor on NORMAL mode only.
After opening the manhole head back outside and look for a ladder. Remember to be taking out zombies and looting whatever you can.
Make your way to the map marker, which will be the supermarket entrance. When you try and open it the alarm will go off and scare the crap out of you and me.
There may be to many zombies here to take out, but it would be best to pick them off if you can. You should have some flares at this point from looting. Toss one then start picking them off.
Make your way to the freezer where all the meat/cows are hanging. Take out the zombies and go into the next section.
You will run into a barricaded door. Barricaded doors can be broken down with the hammer. Scan the area for the hammer, it is located in one of the nearby trash cans. Once you have it, use it on the door.
Eventually you will come to an area with some platic flaps, go through them. We are working our way downstairs at this point to the next CCTV junction box.
Once you are in the basement area, there should be a few zombies. Remember tactics : One lone zombie, use the cricket bat to conserve ammo. Two zombies, use a small gun. Three zombies or more think explosives and flares. Scan the Box, then make your way back to the manhole via marker and return to the safe house.
Defending the Safehouse
People seem to have trouble here, as I did too at first. You may think the Zombies don't stop comming but they in fact do stop.
Pick them off with cricket bat, there are NOT as many as you think. Also there are no other zombie variants then regular.
Anyway to make it easier, even if you do die, less will spawn when you return as the next survivor.
If your playing survivor mode at a slow pace ; exploring survivor. You should have enough Ammo to take them out without even taking damage. Finally if your doing a speed run, I suggest the handgun and be good with head shots.
