Narnia Prince Caspian

This achievement requires you to kill one hundred Telmarine soldiers while in control of a giant. It can be easily obtained in the first level. When you are defending the battlements, you can kill twenty archers with a giant and when you seal the doors at the end of the level, you have to kill another twenty-five. The remaining fifty-five can be killed while you’re out on the main field of battle destroying the war machines.
