Description Ultimate Zombie Defense:
Ultimate Zombie Defense is a Top-down Co-op Survival Horror set in the suburbs of a once quiet city, in the heart of continental Europe. The city and the surrounding 250km landmass have been sealed off in an attempt to curtail the outbreak, although sadly all attempts have failed, until now.
You and your friends are elite members of the military dropped into this plagued location and have only one mission: Locate and destroy the source of the infection.
Well, what are you waiting for? Get to it, Soldier!

Please leave positive review, for me it is important.
