On certain maps in Doom 3 the player is required to collect a puzzle item which they need to use in order to progress (such as to unlock a door, or activate a mechanism). The player can hold one puzzle item at a time and it is shown in inventory in PDA. The puzzle item will be removed upon using in it.

The puzzle items can roughly be divided into keycards and other items.

Keycards

PDA icon used for all keycards.

ACO keycard

The ACO keycard is used to access some offices in Mars City. When the player revisits the area after the invasion, they need to go through one of the offices which is locked by this keycard. Fortunately, the keycard is found on a table in a nearby office which happened to be unlocked.

Maintenance key 4

In Alpha Labs - Sector 3 the player encounters a locked on their way and needs the maintenance key 4 to unlock it. The key is located Hazardous Waste Disposal, but the room is contaminated by toxic gasses coming from two of the barrels. The player needs to remove those barrels by using a manipulator in a nearby control room to access. The key will be lying on the floor in the center of the room.

BRD access card

This card is used to access the Bio Research Division in Delta Labs - Level 2. Fortunately, just like ACO keycard, it is located not far from the door it unlocks, in Teleport Observation, on a bench next to a zombie that pretends to be dead.

Other

Data linker

PDA icon.

When player reaches Delta Labs - Level 1, they need to restart the reactor and restore the power in the complex to proceed, but to be able to access the reactor they need to gain the control access to the doors in this level, and to do this they need to retrieve the data linker. The data linker is located not far from control center, in Delta 1 Access Lobby, next to a body of it's former owner.

Plasma inducer

PDA icon.

In Delta Labs - Level 2 Ian McCormick asks the player to retrieve the plasma inducer to power up the teleporter so that the player can proceed further into the complex. This plasma inducer is located in the power room of Delta Operations, to which the player needs to gain access first.

DLib replacement panel

PDA icon.

In Central Processing one of the doors the player has to go through is missing its control panel, so the player will need to find the replacement. The replacement panel is located on the third floor of Lab A in an opened storage crate.
