Fable III

****SPOILER***

In the main story, after you leave you friend because he has gone blind.

While walking in the desert you will see a ghost of him being attacked by the black ghost enemies.

You can keep on killling these black ghosts as long as you dont go near you friends ghost and stay back. The black ghosts will keep on respawning.

This achievement is pretty self-explanatory. Just make sure to use melee weapons as often as possible. It definitely helps to upgrade your melee damage on the Road to Rule, because that will just let you dispatch your enemies more quickly. It's just personal choice really between swords/hammers/etc. so just pick a weapon that suits your play style. Some people like a weapon that allows for quick attacks, where others will find this achievement easier to come by with slower weapons that do more damage.
