Aphelion: How to Clear Chapters 7 & 8 – Storm and Nexus

The cleanest way through Aphelion Chapters 7 and 8 is to stop treating them like action set pieces. Chapter 7, The Storm, is a route-and-survival sequence built around shelter timing, careful EM scanner use, ledges, and winch points. Chapter 8, The Nexus, shifts to Thomas and becomes an objective run where oxygen management, credentials, debris clearing, and the final winch interaction matter more than speed. If you keep moving between safe pockets in Chapter 7 and avoid unnecessary backtracking in Chapter 8, both chapters become much more readable.

This walkthrough is focused on the failure points most players hit in these late chapters: losing direction in the storm, standing still too long while scanning, getting spotted by Nemesis, and then burning oxygen inside the damaged base because the route is less obvious than it first looks. The broad sequence documented across available coverage is consistent, even if some minute puzzle details are lightly described in public summaries.

What Chapters 7 and 8 are actually testing

These chapters are where Aphelion brings its two playable styles together. Ariane’s side is still about traversal and stealth, but the storm turns navigation itself into the main hazard. Thomas’s side is slower and more methodical, with the pressure coming from limited oxygen, blocked paths, and the need to reach the Nexus instead of simply surviving the space. That means the usual late-game mistake is trying to improvise too much. These chapters reward deliberate routing.

• In The Storm, move from shelter to shelter instead of chasing the objective marker blindly.
• Use the EM scanner in short checks, not long stationary scans in exposed areas.
• When Nemesis appears, think distraction and line-of-sight break, not brute-force escape.
• In The Nexus, progression is tied to the order of objectives: credentials, debris, deeper access, then the final winch sequence.
• Oxygen is your timer. Every wrong turn in Chapter 8 is more expensive than it looks.

Chapter 7 walkthrough: The Storm

Ariane’s chapter is easiest when you treat each exposed run as a short commit. The storm is the hazard, so the correct rhythm is simple: identify the next safe point, move, recover, then plan the next leg. If visibility drops and you are unsure whether the next hold or ledge is actually reachable, wait a moment in cover rather than guessing. The game wants you to respect the environment here.

Move in short bursts between shelter points

The safest route through the storm uses shelter pockets as checkpoints. Before leaving one, face the next ledge, anchor, or protected opening and make sure you know exactly where you are going. If you step out and immediately start correcting your route, you waste time and usually end up taking the longest possible exposure window. The better approach is to commit to one destination at a time, even if that feels slower.

If the chapter starts to feel unfair, it is usually because you are combining too many tasks at once: running, scanning, looking for handholds, and reacting to the weather. Split those jobs up. Scan from cover. Pick the next route segment. Then move. That simple separation does a lot of work in this chapter.

How to use the EM scanner without getting punished

The EM scanner matters in this chapter, but it is also the easiest way to lose momentum. Public walkthrough coverage points to frequency-based puzzle use in the storm, which fits how the chapter is structured: the scanner helps you confirm direction or interactable targets, but standing in the open to perfect a signal is the wrong play. Use it briefly from relative safety, confirm the signal direction, then move to the next piece of cover before checking again.

If you are not getting a clear result, do not keep forcing the scan in a bad position. Re-center the camera, step back into shelter, and try again. In weather-heavy chapters like this, the biggest time loss often comes from insisting on solving the whole scan from a single exposed spot. You usually only need enough information to advance one segment.

Ledges, winch points, and traversal rhythm

Chapter 7 mixes storm navigation with climbing-style traversal, so missing a ledge or interact point can cost more than health or momentum; it can reset your whole read of the route. When you see a winch point or climbing lane, stabilize the camera before committing. If the prompt feels awkward or the character does not align cleanly, step back and approach again instead of trying to force the interaction while the storm is blasting the screen.

It also helps to think of the winch as a path-enabler, not a detour. If a section looks like it should open forward progression but nothing is happening, check whether you skipped the nearby anchor or approached from the wrong side. These sequences are usually readable once you assume the game wants one clean route rather than multiple improvised solutions.

How to handle Nemesis in The Storm

Nemesis is the panic point in Chapter 7, but the encounter is more stealth and space control than chase sequence. The documented route indicates Ariane can use distraction and stealth rather than direct confrontation. That means your goal is not to outrun Nemesis in a straight line. Your goal is to create one safe lane of movement, break line of sight, and keep going.

If the game gives you a distraction opportunity, use it to pull Nemesis away from the route you need, then move immediately while the path is clear. Do not wait too long to see whether the distraction fully “worked.” Likewise, do not sprint into a wide-open area right after using one. The best movement is controlled and purposeful: create space, cross the choke point, get back into cover.

Chapter 8 walkthrough: The Nexus

Thomas’s chapter is a different kind of pressure. Where Ariane is fighting terrain and visibility, Thomas is dealing with a damaged base and a shrinking margin for error. Reviews and walkthrough summaries describe this side of Aphelion as slower, investigative survival, and that is exactly how Chapter 8 should be played. If you rush it, oxygen becomes the punishment for every wrong read.

First priority: oxygen management

Oxygen is the chapter’s real timer, so your route through the base should be as direct as possible. Before opening side doors or checking rooms that look optional, ask whether the current objective requires it. If not, keep moving. The most common oxygen mistake is not a dramatic failure; it is death by three or four tiny detours that each seem harmless on their own.

• Do the main objective first and only search side spaces if the route clearly demands it.
• Avoid doubling back unless you know exactly what you missed.
• If a locked path stops you, think “required pickup” before you think “hidden route.”
• Use every oxygen-safe moment to plan the next room, not just the next door.

Credentials and debris: the two progression checks

Available walkthrough summaries describe Chapter 8’s core sequence as reaching the damaged base, obtaining credentials, clearing debris, and then using a winch to trigger the finale. If your progress stalls, you almost certainly missed one of those gate checks. In practice, that means you should stop searching for a clever bypass and instead retrace the immediate objective chain: where were credentials supposed to be found, what did they unlock, and what debris-clearing step followed?

This chapter becomes much easier once you accept that it is structured like an objective corridor, not an open puzzle box. When a door or passage refuses to become relevant, the answer is usually earlier in the same sequence rather than hidden elsewhere in the base.

Reaching the Nexus and ending the chapter

The final idea of Chapter 8 is that Nemesis is the threat, but the Nexus is the vulnerability. So do not read the finale as a conventional boss fight where the goal is to stand your ground. The route points to disabling or destroying the Nexus through the environment, with the final winch interaction acting as the trigger once the path is prepared.

If the end sequence feels unclear, check the room for the last unresolved environmental step instead of assuming you missed a combat action. In these chapters, Aphelion repeatedly asks you to solve the space, not overpower it. Once the path is open and the required interaction is available, the finale moves quickly.

Common mistakes that cause the most retries

• Using the EM scanner too long in the open: confirm direction, then move. Do not try to finish the whole puzzle from one bad position.
• Ignoring shelter rhythm in The Storm: fast movement only helps if you already know your next safe stop.
• Treating Nemesis like a chase enemy: these encounters are about distraction and route control.
• Forcing winch prompts from the wrong angle: re-approach interact points if the camera or character position looks off.
• Backtracking casually in The Nexus: oxygen loss adds up much faster than most players expect.
• Assuming a blocked route has a hidden alternate path: Chapter 8 is usually waiting on credentials or debris progression.

If a prompt or route seems broken

Because these chapters combine traversal, weather effects, stealth pressure, and objective gating, a missed prompt can look like a bug when it is really an alignment issue or skipped step. Reposition the camera, walk back into the previous safe space, and approach the interaction again. If that does not work, retrace the last completed objective rather than wandering forward. In The Storm, that usually means returning to the last clear shelter-to-shelter route. In The Nexus, it usually means checking whether you actually picked up the credentials or finished the debris-clearing sequence that unlocks the last winch action.

Approached that way, Chapters 7 and 8 stop feeling like messy late-game spikes and start reading like what they are: one chapter about surviving environmental hazards with Ariane, followed by one chapter about disciplined objective routing with Thomas.
