Atomfall is a role-playing game that challenges players to make difficult choices, often leaving them questioning their decisions. Throughout various quests, players face numerous choices that can lead to unexpected outcomes. Some decisions may result in missed upgrades or benefits, while others can entirely block access to specific quests or endings. This ambiguity keeps players on their toes and encourages thoughtful exploration.
As you navigate through Atomfall, you’ll encounter multiple paths leading to Mother Jago. Several NPCs will guide you toward her, as will the Hearing Voices lead. If you don’t acquire these leads, you can still find her by directly heading to her location or discovering leaflets scattered in Casterfell Woods, which will mark her position on your map. Regardless of how you reach her, all paths ultimately lead to the Old Mine situated within Casterfell Woods.
The Impact of Giving Mother Jago the Serum
Understanding the Growth Stimulant



The serum that Mother Jago requests is known as a Growth Stimulant, which you must acquire from the Medical Wing in the Interchange. When you have the serum, it’s advisable to give it to her, as there are no significant downsides to this choice. In fact, keeping the serum provides minimal benefits for your personal use. Therefore, handing it over not only benefits the quest but also leaves the possibility of pursuing her ending open.
At this stage, assisting Mother Jago does not restrict you from other quests or endings, making it a safe choice. It is easy to lose access to various quests due to the multitude of endings available. Thus, it’s wise to consider your options carefully to avoid potential lockouts.
Consequences of Not Giving Mother Jago the Serum
The Risks of Limiting Your Options

If you opt not to give Mother Jago the serum, you will be unable to proceed with her quests. While her quests aren’t essential to completing Atomfall, this choice effectively ends her storyline for you. Conversely, providing her with the serum doesn’t obligate you to continue her tasks. It merely preserves the opportunity to explore the Lake District through her quests should you choose to do so.
Furthermore, it’s important to note that some of her quests are crucial for survival, especially when it comes to powering up Data Center A in the Interchange using an atomic battery. You’ll require her assistance to make progress through this segment, regardless of the ending you aim to achieve.
The Case for Giving Mother Jago the Growth Stimulant
No Detriments to This Choice

Ultimately, giving the Growth Stimulant to Mother Jago is recommended. Since this decision occurs early in her quests, you can be confident that you won’t lock yourself out of other possibilities. Additionally, this choice opens the door for you to follow through with her full narrative arc if you desire her ending. Her quests also provide valuable lore that enriches your understanding of the events that led to the downfall of the Interchange, making them well worth your time.
You can even combine tasks by visiting Dr. Holder prior to gathering the Growth Stimulant, as he also seeks an item from the Medical Wing. He will provide you with a keycard, enabling access to deeper areas. This approach allows you to make the most of your exploration and gather items that won’t impede your progress on other quests.
Throughout your journey in the Lake District, you will encounter several pivotal decisions. Giving Mother Jago the serum is a low-risk choice, enabling potential access to her ending—a narrative that offers unique insights into the game’s lore. If you’re committed to experiencing every potential ending in Atomfall, consider making a save file before this choice, allowing you to revisit and explore all options later.
