Reactors walkthrough: entry prep, tram use, and Power Services route

What Reactors should accomplish for your progression

Reactors is a late-game sector where route efficiency matters more than raw loot volume. By the time players arrive here, most failures come from poor environmental prep, mixed objectives, or delayed extraction rather than from not knowing how to swing a weapon.

In practical terms, your first Reactors goals are usually narrower than they sound:

• activate the keyed tram station in Power Services;
• confirm a safe return route that can be repeated later;
• check Power Cell and forklift utility along the way;
• leave with one durable unlock instead of with a backpack full of random side salvage.

If your gear still feels borderline for Hydroplant, solve that first with the Hydroplant walkthrough and the endgame gear checklist. Reactors is not a good place to discover that your environment plan was optimistic.

Preparation checklist before entering Reactors

Prepare for the part of Reactors you actually intend to enter. The sector's documented radiation, spores, combat and transport obstacles are different problems, not a sector-wide heat requirement. A first Power Services trip starts from Hydroplant access; the useful Office tram is an unlock to establish there, not an assumed first-entry route.

Bring the following:

• Protection and recovery suited to the declared region. The Reactors location descriptions identify a highly radioactive Buoyancy Lab portal, Radioactive Waste around Cloud Reactor, and vision-obscuring spores in Mist Reactor. Select the relevant preparation rather than importing Mycofields heat requirements into every Reactors corridor.
• At least one spare healing cycle. Long late-game hallways punish the "I can finish on low health" mindset.
• A Tram Station Key if Power Services activation is the current objective.
• Enough inventory space to carry the route item you actually came for, such as a Power Cell, rather than clutter from side cabinets.

If tram planning itself still feels unclear, read tram system travel before this sector. Reactors is much less stressful when you already understand which station is keyed and why activating it changes every later trip.

This table is a scope check, not a complete equipment prescription. If a temperature warning becomes relevant in your save, respond to the actual HUD state and equipped resistance. Enemy fire attacks and ambient temperature are not interchangeable evidence, and healing supplies do not replace a blocked route or the protection needed for a specific exposure.

First Reactors route: Power Services first

For most players, the correct first Reactors trip is not "clear the sector." It is "activate the useful station and survive the return."

1. Enter with the Power Services station as the declared priority.
2. On the initial approach, enter from Hydroplant's Spillway C, reach the water surface, and use the red ladder to Power Services. Do not plan to arrive on a station you have not unlocked. On later visits, use your established tram connection instead of adding unrelated scavenging to the approach.
3. When the keyed station is reached, activate it immediately. Do not keep the key in inventory while wandering for bonus loot.
4. After activation, check whether the return route is still healthy enough to bank the unlock. If yes, leave. If not, stabilize and leave anyway once the path is clear.

This feels modest, but it is the unlock that makes every later Reactors visit more efficient. The early win condition is station access, not full sector ownership.

The independent entry route places a Check-In Terminal and return water pipe behind the Power Services kitchen. Confirm that return before following the station sign and using the key. The keyed tram connects to Office Sector near the Data Farm. The sector's internal reactor tramlines are a different network; a broken internal rail does not mean this Office connection failed. Record the check-in, return pipe and keyed station as separate checkpoints, then bank the access objective before pushing into a reactor or taking the Buoyancy Lab detour.

Forklifts, Power Cells, and late-game hauling

Existing site references already note that Reactors contains multiple forklifts, which is a clue about how the sector wants to be used. It supports planned transport more than impulsive looting. That means route control first, hauling second.

Use this decision rule:

• If the station is not active yet, ignore hauling ambitions and solve tram access first.
• If the station is active but the route still feels dangerous, use one short scouting run to map where forklifts and Power Cell opportunities sit in relation to your safe retreat line.
• Only once the return path is repeatable should you convert the sector into a real hauling route.

This is the same principle that keeps Manufacturing and Hydroplant efficient, but in Reactors the penalty for ignoring it is much higher because the environment keeps taxing you while you hesitate.

Decision table: when to keep pushing and when to extract

The most valuable Reactors habit is ending runs after a single meaningful win. This sector rewards specialization, not greed.

Planning your second and third Reactors visits

The first Reactors trip should unlock the line. The second and third trips are where the sector starts paying you back.

On the second visit, treat the newly active station as a measuring tool. Ask whether the return path now feels short enough to support one extra task, such as confirming a Power Cell location or mapping a forklift lane. If the answer is no, you are not behind. It only means the station activation did its job and the route still needs another clean pass.

On the third visit, pick one specialization: hauling, item retrieval, or wider sector familiarity. Late-game players often lose more time by combining all three than by running three shorter trips. Reactors is one of the clearest examples of the game's central progression lesson: stable infrastructure beats dramatic one-run efficiency.

If a later Reactors run starts feeling routine, that is a success signal rather than a sign that you are moving too slowly. Routine is what makes late-game travel cheap.

Recovery advice for common Reactors failures

• Entered without a plan for the current hazard. Regroup at the confirmed return and correct the actual failure: radiation exposure, poor visibility, enemy pressure or an unresolved access gate. Do not spend healing to justify proceeding through a hazard your equipment or route does not address; do not diagnose every Reactors failure as missing heat resistance.
• Used the tram key too late. On the next run, activate Power Services the moment it is reached.
• Turned a route unlock into a salvage run. Bank the station or item first, then come back with a hauling loadout.
• Got lost between trams and side corridors. Reset to the active tram line and remap the area around that anchor only.

Which page should come next after Reactors

Reactors usually branches into one of three next problems.

• Need the paired environmental route before this sector feels comfortable: return to the Hydroplant walkthrough.
• Need broader material sustain rather than more map knowledge: use the resource farming guide.
• Need recovery stability for longer late-game sessions: unlock or revisit Rise medkit farming.

That is the stable loop: gear for the environment, activate the line, bank the unlock, and only then convert Reactors into a repeat route.
