To complete the initial Outpost: Infra-Station Exploration Mission in Arknights: Endfield, finish Main Mission 17, “Mystery in the Building,” then investigate the missing workers, review the Intel comments in the Archive, and deploy the Sub-PAC at the marked site. The quest takes place at the Infra-Station in Originium Science Park, Valley IV.

How to unlock Outpost: Infra-Station

PowerPyx lists Main Mission 17, “Mystery in the Building,” as the prerequisite for unlocking the Exploration Mission. Once available, travel to the Infra-Station camp in Originium Science Park, Valley IV. The quest index also places the mission in Originium Science Park.

How to complete the initial Infra-Station mission

  1. Speak with Noffman at the Infra-Station camp. If you cannot find him, PowerPyx says a nearby Panda can point you toward his location.
  2. Investigate where the workers went missing. Use the scanner to locate clues, then examine the box, torn rope, and file. Read the file after inspecting it.
  3. Review the investigation in the Archive. Open the Archive and read the Intel comments for the Infra-Station investigation. This is a required part of the reported quest sequence.
  4. Return to Noffman. Speak with him at the camp again, then follow him to the open area.
  5. Deploy the Sub-PAC. Place it at the marked position to establish the outpost and finish the initial mission.

These steps follow PowerPyx’s walkthrough, published February 5, 2026. If a step or interaction differs in your game, use the current in-game quest markers as the guide; the walkthrough is third-party guidance, and the available sources do not verify the exact steps against the latest game build.

What to do if the quest does not progress

  • You cannot find Noffman: Check the nearby Panda for directions, then follow the quest marker back to the camp.
  • The investigation seems stuck: Scan the area and examine each identified clue, including the file. Then check the Archive for the Intel comments before returning to Noffman.
  • You have reached the open area: Look for the marked placement position and deploy the Sub-PAC there; this is the final step in the initial mission.

What the mission reward and outpost unlock mean

PowerPyx reports a reward of 75 Oroberyl and 300 EXP for this mission. Treat those figures as guide-reported rather than officially confirmed: the available sources do not establish the reward in an official record or confirm it for the latest game build.

Establishing the outpost connects to the game’s Outpost Management and AIC systems, according to All Things How. That broader context can explain why players look for help with power and production in the area, but those systems are separate from the initial mission’s completion steps.

The initial quest ends when you deploy the Sub-PAC at the designated location. Later Infra-Station activities and broader outpost progression are not part of this walkthrough.
