Straight forward walkthrough with maps and videos. This route can be done in 60 minutes.

Easy 1-Hour Walkthrough

Pistol

Why: This is a shooter, we need a gun (to save time we don’t get the pliers, we shoot mines).

To get the pistol, the quickest way is to release the enemy, carefully move past it, and pick up the pistol and ammunition. After that, you need to open your inventory (usually by pressing the TAB key) and move the ammunition onto the pistol to load it. Close the inventory again (TAB key) and then select the pistol, which is in the first quick slot (usually the 1 key). Lastly, aim at the enemy and fire. A helpful hint is to have your mouse cursor positioned over the second inventory slot beforehand.

Normal way to get the Pistol:

Save: Where you started (1 Diagnostics).

Screwdriver

Why: Needed for Damage Upgrade – we want that as soon as possible. (Also required for White, Teal, Blue, and finale).

Save: Hub

• – Store all ammo, you gonna get more. 

(You should now have your pistol and screwdriver in your pouch, and keep them to the end).

Damage Upgrade + Wrench

Why: The upgrade nearly doubles your fire power. We need it to save ammo. The Wrench is required to continue to the next level (also Forceps + Teal key).

Save: Start (don’t go all the way back to Hub, takes 25 seconds.)

• – Store all ammo, you gonna get more.
• + Take (or rather keep) Wrench with you, we need it next.

Orange Key

Why: To open door to white button cap (which opens a path to a lever that we need up in Security later, as well as a remote control.)

Save: Middle of Engineering, 9 Repairs.

• – Store all ammo, you gonna get more.
• – Wrench.
• + Orange.

Remote Control

Why: The Wi-Fi remote control (aka Clicker) is required to open the door to the bolt-cutter (needed later in Security).

Save: In Medical, 16 Storage.

• + Keep Orange.
• + Keep the Remote.
• After saving go for the Pouch and the Remote.
• While still in 4-Utility press Remote once to open the other door.

Lever + Boltcutter

Why: Both are required in Security later, lever for a forklift, bolt-cutter to open gate to Jammer.

• Round-trip to get lever.
• Remember to press Remote once in 6 Motorics.
• Take Boltcutter.
• Remember to take the blue Receiver button.

Save: Medical 16, Storage

Drop Orange key once you have the pouch (right-click to let it fall on the floor, we need a free slot next. What’s on the floor will stay there for the entire game. We may pick it up on our way back if we need it. Of course you are free to store it in your inventory, it just takes longer.)

• – Store ammo (we still get more).
• – Wifi Remote.
• – Wifi Receiver.
• – Boltcutter.
• + Wrench for forceps.

Crowbar, Forceps, White Key

Why: We need both Forceps (look like siccors) and White Key to get the Teal keycard (which opens doors in Medical later). You can’t miss the Crowbar on your way (need it for White key next and up to Security).

(Optionally save in 15 before 16+14).

Save: Hub.

Drop saw immediately after use + Drop hand immediately after use.

• + Crowbar (to get into Security).

Save: As before in 5 Utility.

Jammer + NVG

Why: We need the Jammer to get the night-vision goggles (NVG).

From Jammer to NVG:

Save: Again in 5 Utility, before and/or after you get the NVG.

Drop Boltcutter once you’re OUT of Security + Drop or leave Jammer.

• – Blue.

Hammer

Why: The Hammer breaks a wall to get the Gas Mask (which we need for the Yellow key).

• All the way down, two stairs to Medical

(You might want to save BEFORE going into Depot! It’s pitch black, there are 6 enemies, and the Hammer is hard to find.)

(Right-click and ‘View Image’ for a larger version).

Save: Down the stairs near Power gate, 5 Storage.

• + 60 ammo.

Power 2 Ventilation

Summary

Here is an overview of the steps we took from one save station to the next:

And here’s another view with just the main items in the order we collected them:

You likely understand the basic controls for aiming (right mouse button), reloading (R key), and sprinting (Shift key).

There are a couple of other useful actions you might not be aware of. If you use the right mouse button on an item, you can either move it to your storage or drop it.

Additionally, when you have your inventory open (Tab key) and hover your cursor over an item in your pouch, pressing the number keys 1 through 4 will assign that item to a quick slot.

Finally, to use an item like a keycard on a colored button, you can look at the button, open your inventory (Tab key), and double-click the keycard to activate it.

Headshots double the amount of damage you deal. So, yeah, that’s very important. You should be fine (with pistol-only and shooting mines) if you have no more than one miss on average and collect every ammo pack there is.

To save ~100 rounds you could get the pliers and use mines against enemies, it takes ~5 minutes longer. As to how to take mines: point your mouse at the edge of the mine until it’s highlighted and press the hotkey for the pliers (yes, have a hotkey for that).
