The Last Stand 2

http://www.maxgames.com/play/last-stand-2.html

This is the successor to the thrilling survival flash game "The Last Stand"! Some things have changed, like for example you can select where to search during the day. You can set up traps as well, and shoot at them during the zombie attack at night. Plus, now you can even equip your survivors with weapons.
Sadly there is not sky visible like in the first game, that will show the dawn of a new day. Still, very entertaining and this time you have to last 40 full days!
