Lua spy may sound intimidating, but it is actually extremely easy once you learn how the vaults work. In this guide, I will show you how to complete Pavlov, Lua with full stealth.

 
 
There are multiple ways to complete each vault. I think the pathing shown in this guide is a good combination of simplicity and speed, while requiring minimal skill.
 
This guide was written at the time of patch 31.1.x. Vaults and Warframes may change in subsequent patches.

I strongly recommend playing a frame that is capable of passing through lasers without triggering alarms such as Ivara (with Infiltrate) or Limbo. It is possible to complete this other frames, but you must take caution to avoid lasers and sentries in vaults.

That said, the failure timers on these vaults are very generous and you should have enough time to complete the vault even if you trigger the alarm.

There are only three vault types in Lua spy. The vaults do not have variations (e.g. vents that may or may not be open) so the same pathing may be used every run.

Vaults A and B are interchangeable. Vault C will always be the same.
Take note of which door type (button or console) you see at marker A / B and reference the guide accordingly.



 

Orokin Spectator enemies may spawn in Vaults A and B. They function like Sensor Regulator enemies and will trigger the alarm if they detect you.
Orokin Spectators only spawn in the present state of the vault. (to confirm)

Lua spy features an unique mechanic known as Void Rifts. These are distortions in space-time which send the player between the present (destroyed) state and the past (pristine) state.

In the present, many things are broken including security systems. However, this also means most things don't function (including the vault consoles). Although the landscape of each state is different, actions in one state will carry over to the other. We will use this to our advantage to manipulate the landscape and easily traverse the vaults.












In this guide, I will refer to the states as present and past and I will inform you which state is required at each stage.

Note: passing through a void rift cancels all active Warframe abilities.

Vault Type A - door is opened by a hackable console
 
Enter the vault and head up the stairs on the left.
 
Go through the void rift to the past, then go through the next void rift back to the present.
  
Continue along the path. Go through the door at the end.
Note: Orokin Spectator enemies may spawn in this area.
  
The vault is here, but we cannot pass through this destroyed door. Go through the void rift back to the past.
 
The door is functioning now.
 
The pressure pad at the top of the staircase will open the door and activate traps around the entrance (shock orbs and cold).
 
Activate the pressure pad and go through the door quickly before it closes.
Tip: you can easily navigate these obstacles using Void Dash.
 
Vault A done!
 
Use the void rift to return to the present to exit the vault.

Vault Type B - door is opened by shooting the button.
 
Enter the vault and use the void rift to travel to the past.
 
Activate the console. Go through the void rift again to return to the present.
 
Go through the door that opened on your left and continue along the path while avoiding lasers.
Note: Orokin Spectator enemies may spawn in this area.
  
Go through the hole in the wall.
 
Avoid the rocks on the right, they are electrified.
 
Go through another hole in the wall.
 
Unfortunately the console is destroyed. Use the void rift to travel to the past.
 
Vault B done!
 
Use a void rift to return to the present to exit the vault.

Vault C
This vault is longer, but not really more difficult. We will travel back and forth between past and present to make things easy.
 
Head inside the vault and enter the door on your right by shooting the button above.
 
Use the void rift inside the room to travel to the past.
  
Hack the console to open the door.
 
Go through the door and shoot the hanging column at the indicated spot to make it fall.
 
That's a lot of damage.
 
Use the void rift again to return to the present.
 
Go through the hole in the floor you just made and continue through the tunnel. Use the void rift to return to the past.
  
Interact with the console to drop the box down. Go through the newly created hole.
  
Use the void rift near the ceiling to return to the present.
 
Go through the hole in the ground. Continue forward through the tunnel.
  
Use the void rift at the end of the tunnel to return to the past.
 
Blow up the volatile orokin container. Use the void rift to return to the present.
 
Go through the hole you just made. Be cautious of the lasers at the top.
  
Go through the door, then through the open door on your left. Continue forward under the fallen door.
  
Continue forward in the next room.
 
Use the void rift to return to the past.
 
BE CAREFUL IN THIS AREA - your abilities will reset when you pass through the void rift.
The railing around you will block the laser beams. However, there is a gap between the two railings where the laser can pass through and detect you!
 
Look up and shoot the button to release the explosive container. Use the void rift to return to the present.
 
Shoot the container and proceed through the hole you just created.
  
Use the void rift in this room to return to the past.
 
Hacking the console will make the button move left and right along the rail. There is a void rift attached to the button which is activated by shooting it.
We want to send the explosive container (and ourselves) through this void rift.
 
Shoot the button to activate the void rift and send the explosive container through, then jump in and return to the present.
  
Shoot the explosive container and go through the hole in the wall.
  
Use the void rift to return to the past.
  
Vault C done!
 
Use the nearby void rift to return to the present and exit the vault.

Orokin Spectators[warframe.fandom.com] are an unique enemy that only spawn inside Lua Vaults A and B in the present state.

 

These enemies are more likely to spawn as Orokin Spectator Eximus, whereas the regular Orokin Spectator enemy is quite rare. Both codex entries require 20 scans each to complete.

An easy way to farm codex scans of the regular Orokin Spectator is with the Ballistica Prime.
The Ballistica Prime[warframe.fandom.com] has an unique mechanic where killing an enemy with a charged shot will create a friendly spectre, lasting 7 seconds. The spectre created is scannable and will always be the regular version of an enemy, even if you killed an eximus.
Note: the spectre must be manually scanned by the player, Helios cannot automatically scan it.

Therefore, we can kill the Orokin Spectator Eximus enemies using charged shots from the Ballistica Prime to spawn scannable Orokin Spectator spectres.

A stealth frame is not 100% necessary, however, it's nice not having to worry about tripping lasers.

There are multiple routes through each vault, especially Vault C.
Many of the alternate routes in the past state have additional challenges (movement + stealth with limited time). Using Limbo and staying in the Rift is a viable approach for navigating these challenges. I may update the guide to include these alternate routes at a later time.
