Only the person who picked up bob's arm and gets the 10 kills, receives the achievement.For anyone who is picking up the arm and it doesn't equip as a new weapon make sure you enable the setting in the options called "Auto Select New Weapons". The level/stage is set with timer. Meaning that it is timing-trials. Bob's arm is needed to open the security door. Even if it opens, just beatdown the Ridden with bob's arm.

Is this glitched for anyone else? I pick up the arm but I don't have it as a weapon. I still can shoot and my melee is still the bat. I have the arm because I can scan it to exit the level but it's not a weapon.

Also glitched for me. Have tried to be host, squad mate, different characters. Thought maybe having the two primary weapons card broke it, but a big nope there too! Have tried 6 times now and the arm just disappears when I pick it up.

It doesn't help when teammates grab the arm and run it straight to the safe house.
The Tall Boys and bloaters don't help either. Haha.
I'll get it. Just have to do another run.

Does everyone in the party get this if one member does it or does everyone need to get it individually?

The 10 kills doesn't have to be in one game. It can be over several. I got the arm and killed 7 Ridden. There was no more Ridden around and the rest of the party were getting annoyed so I finished the level. Tried the level again, got 3 more kills with the arm and the achievement popped there and then.

Anyone else having a bug where you don't wield Bob's hand after picking it up? Every time I've grabbed it it just vanishes and I can't wield it, but still able to scan it at the safe room.

For anyone who is picking up the arm and isn't seeing it as a weapon. Turn on the setting in the Gameplay options called "Auto Select New Weapons". I was having the same issue with picking the arm up and still having my usual Primary and Secondary weapons instead of the arm. But once I turned that option on the arm became my weapon upon picking it up.

In act 2 - the handyman you will be required to find "Bob".

Eventually you will find Bob's arm in the last nest you destroy, it is required to proceed through the chapter. Use it to as a melee weapon to kill 10 enemies.

In this video guide I will show you how to kill 10 ridden with Bob's arm. Bob's arm can be found in Act 2, level called The Handy Man.
This will be part of the story and can't be missed. Once you destroy the last pod the arm will be inside. Pick it up and kill 10 common ridden with it and the achievement will pop.
If you are having problems with the arm not equipping, you will need to go to the gameplay options and turn on auto select new weapons.

This does not need to be done in one, works over multiple playthroughs.
(I killed 8 then 2)

On the Level "The Handyman", three nests neat to be destroyed to locate the key item 'Bob's Arm'. Whilst held, this functions as a melee weapon like the baseball bat. Simply kill 10 ridden with it before finishing the level as this weapon doesn't carry over to the next level.

Mission 2 of Act 2, you need to destroy the roots of the infection, there are 3 of them at a time, a hand will fall out on the last one, according to the plot you need to scan it, but we know what needs to be done) 0

The trophy is buggy on PS5 - it doesn’t take this hand as a weapon, on PS4 it takes it as a weapon, but no matter how many zombies I kill, they don’t give me the trophy.
