13 Nights is one of my favorite based launch Friv Action Games in which you will have to defend the castle from hordes of zombies with a bow, musket and a slingshot. Remember you can use of three warriors strategically to escape from the brute and their ship before your castle is destroyed. Each defender has strengths and weaknesses so adapt to the situation and use the right weapon if possible. Try your best to protect your island in 13 nights.
