Complete the Groundpounder mission in the Altair system to earn the Peacekeeper rifle. Despite the similar names, the Groundpounder reward is the Peacekeeper, not the Peacemaker; Peacemaker is a separate Starfield quest.
Where to start Groundpounder
Travel to the Altair system and land at Research Outpost U3-09 on Altair II. Bethesda’s mission-journal entry sets the scene: “A merchant told me there is a lot of Spacer activity in the Altair system. He also heard an urgent distress call. I’ll have to go to Altair to learn more.” Bethesda Support’s Groundpounder mission page confirms Altair II as the mission location.

The mission moves between the outpost, a research camp, and two orbital encounters before returning to the outpost for its final fight. Follow the active mission markers; enemy counts and encounter details can vary.
- Find Private Mahoney. At Research Outpost U3-09, locate Mahoney, then clear the Spacers outside the infirmary and speak with Lezama.
- Rescue the officers. Follow the objectives to find and rescue Lieutenant Torres and Captain Myeong. Speak with Myeong when prompted.
- Clear the research camp. Travel to the marked camp on Altair II, defeat the Spacers there, and speak with the survivors. Return to Torres.
- Fight the Spacer ships. Take your ship to the marked encounters around Altair V and Altair I and defeat the hostile ships.
- Repel the final attack. Return to Research Outpost U3-09, defeat the Spacers assaulting it, and speak with Torres to complete the mission.
The objective order and reward are listed in Game8’s Groundpounder walkthrough.

Groundpounder rewards
Game8 lists 300 XP, credits, and the Peacekeeper rifle for completing the quest. The guide describes the credit payout as level-dependent, so there is no single fixed credit amount to expect. A second guide also identifies the Peacekeeper as the Groundpounder reward: Game Rant’s walkthrough.

The similar names refer to different things. The Groundpounder reward is the Peacekeeper rifle. Peacemaker is a separate quest associated with Eleos Retreat and Peacemaker-named equipment; it is not the Groundpounder reward. See IGN’s Peacemaker quest guide for that separate mission.
Quick Recap
Rank #3
- TELL YOUR STORY - In Starfield the most important story is the one you tell with your character. Start your journey by customizing your appearance and deciding your Background and Traits. Will you be an experienced explorer, a charming diplomat, a stealthy cyber runner, or something else entirely? The choice is yours. Decide who you will be and what you will become.
- EXPLORE OUTER SPACE - Venture through the stars and explore more than 1000 planets. Navigate bustling cities, explore dangerous bases, and traverse wild landscapes. Meet and recruit a memorable cast of characters, join in the adventures of various factions, and embark on quests across the Settled Systems. A new story or experience is always waiting to be discovered.
- CAPTAIN THE SHIP OF YOUR DREAMS - Pilot and command the ship of your dreams. Personalize the look of your ship, modify critical systems including weapons and shields, and assign crew members to provide unique bonuses. In deep space you will engage in high-stakes dogfights, encounter random missions, dock at star stations, and even board and commandeer enemy ships to add to your collection.
- DISCOVER, COLLECT, BUILD - Explore planets and discover the fauna, flora, and resources needed to craft everything from medicine and food to equipment and weapons. Build outposts and hire a crew to passively extract materials and establish cargo links to transfer resources between them. Invest these raw materials into research projects to unlock unique crafting recipes.
- LOCK AND LOAD - Space can be a dangerous place. A refined combat system gives you the tools to deal with any situation. Whether you prefer long-range rifles, laser weapons, or demolitions, each weapon type can be modified to complement your playstyle. Zero G environments add a chaotic spectacle to combat, while boost packs give players freedom to maneuver like never before.
