Valley of Suspicion isn’t really that hard. It just requires you to use Goggles to find keys.
Some keys are hidden though but it might not be plainly obvious where they are. So now we start a very breif walkthrough of Chapter 5 Act 2.

Map of the Second Block
When you start the first block, its pretty simple that you basically use the goggles to find the right switch to open the door. When your viewing through the goggles, look for a green circle. If you see a green circle, you can press that switch to move on. Eventually you will reach another set of switches that can activate traps. Just use your goggles to find the switch that doesn’t contain any trap near it, and the gate will open.
Kill Bil & Get Key!
When you reach the next block, you’ll have to deal with finding 4 keys to open a gate. The first 2 keys are located by defeating the Bil De Vears. The other 2 keys are located at the entrance by destroying the two traps that shoot at you. Again you’ll eventually reach up to another 4 key door, and you’ll just need to defeat the Bil De Vears to obtain the keys. There are 4 distinct Bil De Vear areas so just walk up to those places and defeat them to get the keys.
There are a lot of plot points in Shadow Conspiracy Act 2, but before you can read about them, you have to put up with a very weird mission. Its not that hard to figure out but once in a while it trips you up with it’s instructions telling you to use the goggles to find the survivors.
You see, your doing the right thing using the goggles through the rubble, but your supposed to fight the enemies in the areas first. Here’s the map with the locations of each survivor, counting down from 6 to 1.

The Key to this mission is making the area safe for the Survivors.
First you defeat the enemies in all available areas before you open 6, that includes fighting the monsters in the first room and the room up top. After both these sections are clear, you can use your goggles on the annoying beeping sound that keeps nagging you to death!

Use Your Goggles to Find the Survivors beeping your pager!
You next move onto 5, then head over to 3. Fight more enemies, and don’t forget the top of the room, then use your goggles on 3 and 4 when everything is clear and when you have your key. Go down and head over to 2 after you defeat the enemies in your way including the small room to the right. Use your goggles on 2, then head down to 1.

Fight the enemies in 1’s room, after everything is clear you can use the goggles on 1 and now you completed the mission under the time limit! Congrats you have completed Chapter 4: Act 2!

While your on Hive Laia, (see even the game hates Laia), the 2nd part of the mission has you pressing a few switches before their power levels deactivate. Its very annoying and takes very long to figure out if your doing it alone. Luckily there is a way to push all switches under the time limit. Just make sure you aren’t lagging and have nothing else to distract you.
Tips:
The first order of business is to defeat all monsters. Do not worry about pressing switches or anything. Just fight. Eventually you will reach a large room where you can see a red gate to your left and another red gate in front of you. The gate that needs to be open is the one in front of you. Walk over the green switch and walk off of it to make it turn off. The gate that was in front of you should now be open. Ignore that small room for now and defeat the monsters in the room in front of you until your back where you started. Open up your map screen so that you can see where you should place Laia to stand.

The Purple Dot is where you place Laia. After you set her there you can run over towards the first switch.

As soon as you activate the first switch, run to the teleport behind you and activate 2.

Then activate #3, then exit through the teleport nearby. Straight infront of you is switch #4. Activate it and the mission is complete!
