I agree this guy only comes on and comments when peoples creative juices are flowing and more than once he's made it sound like were going down the right path. I believe this guy is in a whole other part of the egg then we are. I just want him to give us more hints on the very next step.
We've completed the achievement and now what. I think he might have hinted at something I posted with EMPing TEDD on the bridge, Jetgunning him, Using the turbine on him, all while he has the "red eyes" he's posted previously. I think that might be the step that we're missing because people are quick to dismiss this idea, but when you break it down that's a lot of different things that can be done out of sequence, ya know what I mean?
You can litterally do this portion of bridge actions like (mathematically) 16 different ways. Piss him off first then EMP then Jetgun then Turbine or EMP, Turbine, Piss him off, Jetgun. You can do a bunch of different ways. If we can slim this idea down and confirm the correct order we might be closer to making an alternate route.
