Halo 3 ODST Good Samaritan Achievement

Also check out my achievement guide http://tinyurl.com/haloguide This one is not easy uless you know about it before you start the campaign. Killed no Engineers in the city(mombasa) at night during entire campaign, alone or with another ODST Sorry, I am not showing the parts in mombasa but I would not kill any period, mombasa or not. I have put some more details about this achievement on my naughty naughty vid. Some one on Trueachievements.com says that the ones that you kill towards naughty naughy don't count against you but I think it is easier to not kill any of them from the start and worry about naughty naughty later.
