I had the social interaction upgrade, so that's how I got it. Not sure if you can do it without it, but I'd imagine you could with the right responses. The game usually doesn't force you to have one certain upgrade to accomplish something.
SilverJinzo posted... I really didn't see any option besides the basic "you got it" and "What does this chip do?" I did the latter and she didn't give me info. And then it was over.
Yeah, I've heard more than once that you can ONLY get the trophy by using the Pheromone option that comes with the Social Enhancer. It also has some other uses, besides simply making some conversations easier. For example, remember that bouncer at the Hung Hua Hotel who you talk to in order to find out where the missing girl is? When the Social Enhancer, you can get him to spill the beans without paying him the 2000 credits! And I hear you can get Tindell in Detroit to give you the footage without doing that favor for him with the SE. Haven't confirmed yet. I would right now, but someone else is using the TV.
