The ninth scene of the second Deadlight act (Hunters) is called Human Flow.
The scene can be unlocked by completing the previous scene, named Lydia.
While playing this specific Deadlight level, we can find 2 collectibles, which are in fact two hidden secrets.
In the following Deadlight collectibles guide, we reveal the location of each hidden secret in Scene 9: Human Flow.
Human Flow Scene Description
I keep seeing Lydia. Visions. Strange moments that make me feel like Im losing my mind. I think its because I miss her. I think its because Im scared. But it hurts when I think about my girls.
I saved the Rats son and hes told me where I can find my friends, maybe even Shannon and Lydia. I have to keep going.
Total number of hidden collectibles: 2
Hidden Secrets: 2
First Hidden Secret
The first hidden collectible in Deadlight: Human Flow, is a tape containing stories for children. We can find it if we check the left side of the third floor in the parking lot (G3), after we find Randalls gun.
We make sure we take it, and then we advance following the tunnel to the right (same floor).
Second Hidden Secret
To get the second collectible, it is very important to know that when we exit the parking lot, we have to go left, even if our goal is to the right.
To do so, as soon as we exit the underground parking lot, we climb on the bus, then jump on the pillars, and continue to move from one pillar to another without falling.
When we reach the last one, we yell, so the zombies nearby can hear us, and jump over the fence. After we clear the area, we continue to advance and eventually we reach a street.
We cross it, and enter a small store. We kill the Shadow inside, and on a shelf we can see a small red box.
The only way to get it is to tackle the shelf. When the red box hits the ground, we pick up the I.D. of the strange inside, and retrace our steps. We continue to advance until we reach the stadium, where the action in the next scene (Playoff) takes place.
