Step 1-2
Black Box & An-G
Pick up the Black Box in the Courtyard, behind the warbird debris.
Give the Black Box to An-G in the Morgue.
Step 3
The 4 Keycards
Acquire the 4 keycards. Picking one up increases the Access Level number at the bottom-left of your HUD by 1.
Note
If the character corresponding to a keycard is in the match, only that player can obtain that keycard. If that character isn't in the match, any player can grab it.
Decker's Keycard:
- Solo: Buy one of the two trash chutes (located in Administration and Exo Testing) and immediately back up so you don't go in. Once it closes, buy it again — this time go through it. If done correctly, you'll be taken to the Incinerator. The wall will slowly close in on you (it can't kill you — it teleports you out instead). Shoot the ground until Decker's Keycard flies up, then pick it up.
- Co-Op: Split the team into two groups at the two trash chutes (Administration and Exo Testing). Buy and enter both chutes at the same time. If done correctly, everyone is taken to the Incinerator — follow the same steps as Solo to retrieve Decker's Keycard.
Kahn's Keycard:
- On an Infected round, all players must become infected at the same time and press 4 buttons in Administration so they're all lit up green simultaneously.
- If a player cures their infection, the button(s) they pressed will need to be pressed again.
- The number of buttons each player presses depends on the player count:
- 4 players — 1 button each
- 3 players — 2 for one player, 1 for the other two
- 2 players — 2 buttons each
- 1 player — all 4
- Once all 4 buttons are green at the same time, a window opens in Administration near the Courtyard revealing Kahn's Keycard — pick it up.
Lilith's Keycard:
- Obtain the EM1 from the 3D Printer.
- Constantly shoot the EM1 at the 3D Printer while simultaneously buying it. Unless the 3D Printer moves, it will contain Lilith's Keycard to pick up.
Oz's Keycard:
- Shoot out the metal bar underneath the nearest Holding Cell in Holding.
- All players must purchase Exo Slam (available in the Main Hub).
- All players must Exo Slam into that Holding Cell at the same time. If done correctly, the Cell sinks into the ground and another rises temporarily — pick up Oz's Keycard from the new Cell.
Step 4
Grinding to Access Level 49
Once all 4 keycards have been obtained, zombies will start dropping keycards — run into them to pick up. Melee kills are guaranteed to drop a keycard.
Every player needs to bring their Access Level to 49.
Step 5
Handscanners (49 → 50)
Once every player is at Access Level 49, each player must interact with the handscanner specific to their character to bring their Access Level from 49 to 50:
- Decker's Scanner — Exo Testing, stairs at the back of the room
- Kahn's Scanner — Administration
- Lilith's Scanner — Morgue, at the top near Exo Testing
- Oz's Scanner — Holding, near Exo Health
Step 6-7
Final Steps
Once all players reach Access Level 50, interact with An-G again until you hear the warning message.
After the warning message, all players must interact with the Exo Suits at the same time until you hear "Experimental weapons upgrade station online".
Go to the Courtyard. Once the Warbird is hit by the missile, the Main Quest is complete.
