Well i´m about half way done the inside of the mall is almost the outside (city) still needs a lot of work but it´s propably gonna take some time because i´m also working on a jurassicpark map.
Okay so you are in a zombie infected city all the ways out are blocked by cars and destroyed buildings. The only way out is being pick up by the last emergency helicopter witch arrives here in about 5 min. You have to get to the mall roof were you are going to be rescued. The only way to the roof is through one of the many stores emergency exits, so get in to a store!!! make a barricade!!! and wait for the exits to open
