(adsbygoogle = window.adsbygoogle || []).push({}); Hello, most ppl who have played this game before know that guns (most but not all) may be stored for later games inside of a fridge at the Farm.
What some people do not know is that offline gameplay restricts this option ( You can put your gun in, but it will NOT carry over to the next game).
So a quick tutorial to do the Unbreakable shield glitch was in order for offliners...
This requires you to play with a partner or another controller... and of course you can do this online, but that should go without saying (I only say so, so I don't see the ? in the first place)

1. Play like normal (Keep the pistol or don't I don't care its your game)

2. Rack points for the P.A.P. (Pack-a-Punch $5000)

3. Retrieve your pistol and P.A.P. (One of two ways, have the gun still, or die)

4. Store your Mustang & Sally in the fridge at the Farm.

5. Instead of quiting and taking forever, die. Well, not all at once obviously (Result = GAME OVER) just leave someone to get to the next round.

6. Respawn and grab a shield from the Gas Station at the Dinner section of the map.

7. Return to the farm with your shield, place the sheild nearby, but not recklessly in the way.

8. Grab Mustang & Sally out of the fridge and put them back in the fridge.

9. Pick up your shield and now it is indestructable.

I do not take any credit for the original shield glitch, I know its not mine... I just want everyone (including OFFLINE) to have fun as well. Also keep in mind that when you die you will lose points, along with your teammates losing points as well, so If you are to do it this way it is recommened to stick all points in the deposit box at the bank before dieing.

part 8 of this glitch dont work for me i have the pack a punched pistols in the fridge when i started a new game i get 2 the fridge but im unable 2 take them out as the pistol u start with can not be stored

The other thread that I was corrected in has informed me that there was an update... This may have killed this glitch. IDK. Havent tried it. But as of the last time I played this will work. And the way you are describing what you are doing is not what I wrote...
You started a brand "New Game"... my method uses either a player in your party to stay alive while all others get there mustang and sally, put it in the fridge, then die leaving the one player I mentioned Alive (NOT Reset, Restart, New Game). This player then kills the last zombie to respawn all other players with there starting pistol therefore at step 6 (While in the same game).
There is no restart, there is no new game. Just the game that you started when you originally PaP'ed your gun to get mustang and sally.
The whole point is to avoid the having to end the game to do the glitch (for Offline/Online to be able to do this glitch).
