Can I save Binh?

There's a specific sequence to this that I don't think anyone has explicitly mentioned.

Upon entering the room with the Tinker, in one corner of the room (across from the prison cell) are a set of three computers.

• One computer is larger than the others. You must use Computer Science on this first.
• Then you need to check the other smaller two (right click to look at the terminals). One will be a "capacitive overload" and the other will disable the "wi-fi." Use Computer Science on the wi-fi computer.

The larger computer can be destroyed by shooting it, but this kills Binh. Hacking the other computer also kills Binh. When Binh dies, you'll get a "Log Book Updated" notification. Doing the "wrong thing" makes the fight easier by damaging the robots and/or applying negative status effects to them.

I was also careful not to shoot towards the larger computer, lest I damage it by mistake.

Tinker will also explode when destroyed, so I made sure she(?) was away from both Binh and the larger computer prior to killing her. (I don't know if this mattered, but it seemed worth it anyhow)

I did the hacking before combat initiated. The "wifi" hack caused Tinker to notice me immediately, so set your team up for combat before doing this hack. You can also do the hacking while combat is going, it takes 4 AP per attempt.

Tinker will also pause when you get her down to critical health, although talking to her made her blow up in my face, so on my final run through I just shot her rather than attempt to initiate conversation.

Yes, it is possible.

As far as I can recall there're 3 computers in the corner of the warehouse where you can find Binh, and you have to hack all of them (in right order!) to prevent Tinker to kill Binh remotely. You can hack one before the fight, and after Tinker drops down to certain health, she will stop fighting, then you can hack the others. Repeat 2-3 times (hack->fight) till you done the hacking job and you're good to go.

Yes there is.

I went into the room, setup my team by the entrance, sent my tech up the LEFT wall (by the door), turn left at the first left, there are 3(?) computers there that can be hacked, iirc I hacked 1 or 2 of them before being noticed, but this turned off his "network".

Once noticed fight started I killed everything, and Binh was on the table alive with a robot heart, also guy in cage was normal. (for him) (though maybe he always is)

To be honest I'm not sure if it was the hacking that saved her, or the fact that I never talked to the tinker and only fought.
