Bionic Commando walkthrough - The Vault (1/2)
Collectible #1/3: Use the nearby rocks to defeat the Biomech, and then make your way towards the collectible of pod drops up ahead. After you stock up on the weapon of your choice, head over to the rock wall opposite the pod drops. The 1st collectible is about half way up the rock wall, on a ledge.
Collectible #2/3: Fight your way past the grunts in the canyon. When you get to the next trio of pod drops, make a right and head to the ledge. The 2nd collectible is right at the drop off on the ledge.
Collectible #3/3: When you get to the circular metal door, lift up the crate closest to the door. The last collectible in the area is hidden under the crate.
