Isn't it that the Good Samaritan achievement unlocks if you do not kill any encountered engineers over the course of the whole campaign until Data Hive? Well, the engineers tend to self-destruct probably because it feels helpless when we kill an entire squad of brutes and grunts. Does this count as a kill or what? Any tips on avoiding this situation?
The achievement requires you to not kill any Engineers in Mombasa Streets and I can't think of any time where they do this at night. If they do do this at night, whenever you see one, find an other way around them.
When I first played the ODST Campaign I killed the engineers because I did not know of this achievement. I started the entire campaign over and played through it on easy. The only thing you have to do is run through it like you have never played the campaign before. I started at 7:40 and finished by 9:30. The achievement does not take too long to do but it will test your patience. It is very boring. I did not even go near the engineers. If you do not shoot them at all it will not count that you killed them. If you kill them it will show up in the bottom right corner that you killed one. (if you have not done the naughty naughty achievement already) If you kill the entire squad of covenant sometimes the engineer will self destruct. This happened to me on Kikowani Station and scared the **** out of me. Don't worry, it does not count that you killed the engineer. Simple tip: run through the campaign on easy as fast as possible.
to get the achievement all you have to do is not kill them... this does not necessarilly mean not shooting them apparently because i shot every single one but didnt actually kill them and got it, i shot them a bit then killed the brutes and it blew up.
I'm pretty sure that as long as you don't fire the last shot before the engineer blows up then it will not count against getting the achievement. Engineers blowing up after their squad is killed doesn't count either.
actually i was replaying the campaign to get audio files and i didn't shoot any but one blew up any way and the counter for naughty naughty poped up.
