Building The Lightning Staff from the purple staff parts and using the tank: http://codzombified.blogspot.co.uk/2013/09/building-lightning-staff-purple-parts.html
here is the map layout for the workshop building, top and bottom floor. This building provides the crucial access to the main dig site and to a build table and a collectible to activate the levels song which makes a funny laser PEOW sounding noise when activated.
The Five-Seven pistol is also located in this area and costs 1100 to buy.
Here is the map layout below:
The good news is there is no robots waiting to squich you like a bug in any part of this building, however the corridors are quite tight and can prove a bit trecherous if more than one of you are stuck in here with no bullets. If you have no bullets and you get trapped in here, you will be on top of a zombies pizza faster than you can say BRAINS!
Enjoy guys, am still working on the rest of the map.
