Hi!
I've seen a lot of games struggle with this map. One strategy that I've been using lately that has been successful is to ignore the top two buildings until you've emptied the zombie reserves. Instead open the middle building and bottom building on the first and/or second turn. You can move down 1 square, search the middle building that faces the center square for weapons, and since the zombies are spawning slowly, you have time to get equipped and kill everything.
It isn't sexy - your survivors don't get to the red threat level - but it works well. Just thought I'd share for anyone needing some help with that level.
