How to unlock the Big Bo Rescue achievement in BINARY DOMAIN - Definitive Guide
*spoiler alert*
At the end of chapter 5 you will fight the Cerberus dog like mini boss. Once you have defeated it and you receive the RPG from Rachel a cutscene plays where Cerberus gets back up and grabs Bo. Your squad mates tell you to carry on and they will fight Cerberus.
You need to ignore them, turn around and go back to where they are fighting Cerberus. Stand right in front of Cerberus and unload a much as you can into the glowing area of its head until it drops Bo. If it disappears over the edge with Bo then a checkpoint will kick in and you can't reload it and the chance is gone.
you can load up this section from the chapter select once you have finished the game once it's area 5-4. Just load it on Cake walk, it may take a few tries but you'll get the hang of it eventually and get the achievement.

Scene-specific, missable trophy.
This trophy can be earned in Chapter 5, Scene 4 - R&D Floor, Amada. This is right after the Cerberus boss fight. Rachael will give you her rocket launcher to take out the satellite dish on the roof, but when you go forward the Cerberus comes back and grabs Bo. You have to shoot the Cerberus to get it to release Bo. Even on Cakewalk, I found this trophy to be rather difficult, but I believe it was because I tried to get it using Chapter Select, which always starts you with a completely downgraded weapon. Taking too long to finish off the Cerberus will cause you to miss out on the trophy. If you feel as though you are taking too long, either reload the checkpoint or switch to the rocket launcher and kill Bo. You will restart right after the Cerberus grabs him.
If you are using Chapter Select and are struggling to get this trophy, here are a couple tips which may help: As soon as you reunite with your team at the beginning of 5-4, you will see a shopping terminal on the right and a sliding door in front of you. If you pass through the sliding door it will close behind you. Kill the enemies in the hall WITHOUT passing through the door, and you should have enough credits to upgrade your firepower twice. Additionally, you can try using the rocket launcher and aiming at the Cerberus' body, after shooting it in the head for awhile.
Keep in mind, this section is timed; you have (15) mins. to get to the Cerberus, defeat it, rescue Bo, and destroy the satellite dish.
This achievement is missable, during chapter 5 you will fight a Robot named Cerberus, it is a Tiger like robot. You will kill it and will move on to destroy the dish. Cerberus will attack Bo, do not listen to racheal and continue on with the mission. Go back and aim at the head of Cerberus, but you have to avoid shooting Bo, this can prove difficult as Cerberus keep swaying.
