Act 3 - Chapter 1 - The Vault | Act 3 - Chapter 1 Bionic Commando Guide
Last update: 11 May 2016
Hidden bonuses: 3
Level walkthrough: Get ready, because you'll have to defeat a few Biomechs at the start of this new level. All the mechs will appear in standard versions, however you'll still have to be very careful. I would recommend that you remain near the area where you've started, but watch out not to step into irradiated zones.
Don't worry if you run out of ammunition for your grenade launcher, because there are A LOT of pods in the area. Reaching them shouldn't be a big problem, even though you'll have to kill a couple of guards. I would recommend taking a rocket launcher and using it right away on the mechs.
Once you've won inspect the area to the left of the pods. Get to an upper ledge using your bionic arm and you'll find the first bonus item. Drop down and proceed towards a small canyon located next to the pods.
There are about ten guards separating you from the second set of the pods. You won't encounter any other mechs, so you may use your most powerful weapons to secure the area. Once you've won inspect the area near the cliff to find the second bonus item.
Obviously you can rearm yourself again using the second set of the pods, but it won't be absolutely necessary. Keep heading towards the mountain. Before you enter the complex make sure to check all boxes, because the final third bonus item will be hidden under one of them.
Proceed to the underground complex. You'll find pods here as well, so you're free to choose the weapon you like the most. Go to the room located to your right and you'll be rewarded with a cut-scene. Go back to the main corridor and head further into the complex. The first group of enemy soldiers will greet you near a new passageway. Use a HIKER or a machine gun to kill them.
When you get to a large dome travel to your right. Spencer will encounter other enemy units along the way, however killing them is going to be very easy. You don't even have to use your guns, because there are plenty of throwable objects in your vicinity. End this level by heading towards the door.
