A Light in the End of the Tunnel Mission Walkthrough

From Noontide Base, travel south to find a train carriage. Follow the carriages south until you pass the last one.

Enter the large building ahead; this is Quiet’s Camp. Speak with Quiet behind his desk and accept his quest to retrieve a psi-installation emitter.

To find the emitter, you must locate Peat, the previous operative. Travel approximately 1 km south from Quiet's Camp, staying on the road and avoiding anomalies.

Upon reaching a suspiciously quiet checkpoint (an auto-save point you restart from on death), search the tower on your right. Enter the upper room and find a recorded interrogation message on the desk regarding Peat.

The message mentions Rookie Village. Head north/northwest back to the main road and find Rookie Village.

Locate the doctor's building (marked with a first-aid sign) and speak to Whale. Inquire about a wounded stranger.

Peat is in the adjacent room, lying in a bed. Speak to him to receive the code for the bunker containing the psi-installation emitter.

Head west from Rookie Village to the Abandoned Tunnel complex. Before entering, consider stashing excess gear as there is loot inside.

Find the tunnel entrance at the back of the complex, to the south. Equip bolts and throw them to clear anomalies along the path to the door with a red light.

Enter the code 1268 to access the bunker.

In the first room, gather supplies. Enter the door to your left and proceed to the next room, a storage area, and loot supplies.

Continue to the next room, then enter the office on your left, followed by the adjacent garage.

Defeat the 'zombie' enemies in the garage. Loot their corpses.

Across the garage, find a locked door with a padlock. Shoot the padlock to open it.

Inside, jump on crates to avoid electricity and reach a backpack with supplies in the back-right of the room.

Exit the room back into the garage and proceed south. Loot supplies from shelves.

Go through the red container, cross the wooden plank, and use the carriages as a bridge to continue south.

At the end of the carriage, jump right to a room with a window and a yellow hue. Eliminate the unaware zombie inside.

Enter the door to the right of this room. Proceed carefully and eliminate the zombies within.

Find a hole in the back of the room. To the left, shoot an explosive canister to access a stash.

Go through the door to your left (where you shot the zombie through the window). Loot Vadym Brahin’s PDA from a corpse.

Press the large red button to open the double doors outside.

Return to the area where you shot the zombie through the window.
