The Meeting...

Logan certainly shared his plan with the others and puts the monitor back when Felix disagree with his idea. He disagree though obey. Felix. This is just a monitor, you know?! Information is in the computer in the hard drive. Anyway, good luck to find power source for it.
Logan turns his attention to the phone - a strange device for him. Never seen one he is trying to push the digits and symbols visible there.

Walter is keeping watch at their backs, as Felix asked. Though he is also curious about the equipment in the container, and doubly so when they are start to glow. The self-titled historian is also alarmed when Logan seems to be about to destroy the screen.

"I don't know what you were thinking, but let us not tear apart this place unnecessarily yet. Even if all of this is strange, we could work with it through means other than violence..."

By now, Walter could probably tell that Logan is a little... uncivilised. His hairiness and bold maneuvers reveals animalistic characteristics. Walter won't remark about that, but has a feeling the creature in video he saw might be closely related to Logan.

Just wanted to see what's inside... Logan says in a tone he would talk to a teacher who just scolded him. Then shrug shoulders and goes to the other container for some privacy Don't you worry, will not break anything!
He sits on the chair at the second container, takes keyboard and imagine him being a hacker from a movie start typing commands like "on", "start", "boot", "open" hitting enter after each. He knows that being occupied with something help him calm down, even of that something is pointless.

"If I had to guess, based on the footsteps leading here and the other terminal, we need to input the correct access code simultaneously. Like nuclear launch codes. Maybe they even change the passkey each time. Let's try listening at the phone. Maybe we'll hear a voice prompt, or the code will show up on the screen."

"Walter, will you do this terminal while I do the other?"

Felix joins Logan in the other container. "Logan, we're gonna try something but we need you to keep a lookout. This could still be an ambush. Can you do that, buddy?"

whatever man Logan moves out of the containers loudly dropping keyboard on the table. He climbs up the middle container and sits down on top of it.

When Logan sits down in the other container the computer screen is now on. The screen is completely white besides the Atlas symbol on the top right hand corner of the screen. In the middle of the screen is a command prompt with a reticle waiting for imput.

Walter is in Container A. The computer has been messed with but the screen is blank.
Felix is in Container B. The computer screen is on. It is completely white besides the Atlas symbol on the top right hand corner of the screen. In the middle of the screen is a command prompt with a reticle waiting for imput.

Logan is sitting on top of the middle Container keeping an eye out for trouble...

With Walter alone in a container, he will carefully see what he could do with the computer set up. He will see if he can power on the computer. The glowing mouse and keyboard are a sign that they are on, so it is a curiosity how the screen is still off. Walter will tap on a key and any other buttons that might work.

(Edit): Walter will sit on the chair at the desk, since Felix mentioned that it is what turned it on. And that it is better sit down than stand when checking out a computer.

Walter does not see a button to turn on the PC. When he types on a few keys nothing happens..

The computer is waiting for input, so Felix picks up the receiver. But he doesn't type anything until he hears from Walter.

As Felix picks up the receiver the following message is played in a cheerful male sounding robotic voice.

"Atlas Warehouse Zero One Three is currently in a Level 5 Code Red Lockdown. Entry and Exit into Atlas Warehouse Zero One Three is currently prohibited by all sentient beings. For more information pertaining the Level 5 Code Red Lockdown please select Two Two Seven.
The message repeats...

A few random letters appear on the Computer screen in front of Felix. "Asdf"

Felix dials 2-2-7.

Over the phone there is a click as if switching lines or being transferred. Then a panicked and stressed female voice starts talking
"Acting Director Paige Parsons. Authentication code 036969." You hear screaming and gunfire in the background then her voice comes back on "Something got in. We don't know what it is or what it wants." The sound of a small explosion, Yelling and more gun fire. "We can't let it or anything else escape. Its getting closer" More gun fire, people yelling and some grotesque wet sounds. The lady comes back on talking a lot faster like she doesn't have much time. Access Override code 050125786775. Kill all code 341756249055. Main Terminal. Don't let them... The sound of a door or wall smashed open and flung, much louder gun fire, louder screaming, hideous sounds of breaking bones, people pleading or begging for their lives, ripping and tearing of flesh. Then silence..."

A few seconds pass of silence when the cheerful male sounding robotic voice appears. "To Replay the message please select One. Otherwise you may hang up at anytime. Thank you."

Meanwhile, Walter will pick up the phone at his side too, to hear if there is anything. If it is the same message from Felix's side then he will put it down, just to be safe that his voice is not recorded. And then maybe they will update each other about what happened.
