With the release of the spiritual successor of Left 4 Dead, Back 4 Blood, the need for Trophy Guides has never been greater! There are some weird achievements gamers can get whilst play this fun new game and some of you might need some pointers here and there. Well, here is exactly what you need to do to get one of the rarest Trophies in Back 4 Blood, “A Humerus Weapon”.
A Humerus Weapon Achievement | Trophy Guide – Back 4 Blood
To get this achievement, you will need to kill 10 Ridden using Bob’s Arm.
This whole achievement run is weird but here is how you end up with Bob’s Arm. In Act 2, you will start the quest “The Handy Man” where you’ll have to destroy 3 Nests.
Once the final Nest is destroyed, the Arm will be inside there, as shown in the picture below:
You’re supposed to use it to open the Saferoom but you’ll need it for something more grim. Just kill 10 Ridden with it and, when it’s done, you will instantly get the Trophy.
