Doesn't Play Well with Others

 is an Fallout 3 achievement on Xbox 360 and PC and a trophy on PlayStation 3.

It is granted for killing 300 people, these can be humans or (non-feral) ghouls. You can check your progress with your Pip-Boy under Stats, then General. For some reason, When I killed a pair of mirelurk hunters in the Rivet City bow, I got the perk after I killed them. Are they clasified as people?

The easiest way to do this is to make a save, then go on a large killing spree. Good places to visit are: Megaton, Tenpenny Tower, Rivet City, Underworld, Big Town, Citadel etc. You'll lose a lot of karma, but that is what the save is for since you only have to hit 300 human kills. You can then reload your previous save, and you will still have your achievement/trophy.

For an even easier way to achieve this method on the pc, simply type in "player.placeatme 000c1121 25" this will spawn 25 easy to kill "insane survivors". Just take out your Gatling gun and go to town, however to may want to do this far away from anyone so you do not kill any innocents. (continue until 300 kills are recorded)

If that sort of thing isn't your style, you could always visit evil NPC-rich areas such as Evergreen Mills, Fort Bannister or Paradise Falls for plenty of people to kill, with no karma penalty. Being good also provides you with a steady supply of random Talon Company Mercs, which become fairly weak later in the game.
