The Lord of the Rings: Conquest

Most easily done in the last level of rise of Sauron the Shire. As soon as the level begins there is a fence with some high grass on the right in front of the first hobbit house jump the fence and run in laps around the inside edge of the fence and hobbits will keep jumping the fence making easy kills for your fire bombs.

Ents cannot enter this fence area and I never had one pay attention to me in this area. If you stand still guards will enter the area and you will have to kill them, running laps around makes it so they almost never enter.

found a way to get all of the single player kills for the specific character you choose. on the second level (war of the ring) were you will be asked to capture the area surounded by the flag, but instead of doing that with whatever character you started out wiht be it the warrior, archer, mage ect. dont capture the rally point. instead as you look past the rally point you will see a metal looking blockade and enemies will flood out of here ever couple of minutes so lets say you have the warrior, just stay alive and rack up a combo or get 100 kills without dying. i did this for all the single player character kills and it works great. if you have any ?'s just send me a messag ill be glad to help.

The easier stage to gain this achievements is with Sauron last campaign at the Shire. Have your scout go to the left side of the map (before the target house). Stand near the broken stone stairs where the hobbits keep jumping down. Use your bomb on the hobbits when there are more than five. Back away to replenish, then repeat. While doing this be aware your surrounding for the ent and captain.
