Quarantine Zone: Complete Modern Prometheus Mission Guide
Published on · Updated on
The Modern Prometheus mission in Quarantine Zone demands prep. See the walkthrough, what to bring, and how to survive to extraction.
The Modern Prometheus mission in Quarantine Zone starts at the operations terminal and requires prep before entry: stock up on resources, check your loadout and follow objectives in the marked order — each step unlocks the next, and extraction only happens after completing the main objectives. The full guide below covers the walkthrough, what to bring and how to survive.
Prep before accepting the mission
- Fill your inventory with healing resources: the quarantine zone has no reliable resupply points.
- Check your primary loadout ammo: starting the mission with a half-empty magazine is the most common mistake.
- Check the region map: the mission entry points appear on the map before you accept — choose the access closest to the objectives.
- Bring one long-range and one short-range weapon: the zone corridors alternate between long-distance shots and close-quarters fights.
Before leaving the terminal, also review what you will NOT bring: heavy progression items stay in storage, and the freed space becomes ammo and healing. The Modern Prometheus mission does not reward a full inventory — it rewards survival. Every slot taken by something useless is a slot that could have been a potion during the escape.
Understanding the objective types
The Modern Prometheus mission mixes three objective types: collection (interacting with samples and documents), elimination (clearing marked points) and extraction (reaching the exit). The marker order sets the flow, and each collection unlocks the next point — skipping a secondary objective does not block the mission, but reduces the final rewards.
Mission walkthrough
- Accept the mission at the operations terminal and head to the zone shown on the map.
- Enter through the marked access and follow the objective order — the first marker unlocks the next area.
- Use cover in fights: the zone has enemies on fixed patrols, and drawing attention early pulls reinforcements.
- Collect secondary items along the way: documents and samples count as a bonus and help character progression.
- Head to extraction after the last main objective is completed — the exit point is marked on the map.
Tips to survive until extraction
- Do not push head-down through narrow corridors: most deaths happen in close-range shootouts with no cover.
- Listen to the radio warnings: zone changes are announced before they happen — the radio warns when an area is about to close.
- Save your best healing resource for the escape: extraction can be ambushed, and reaching the exit with no health is the fastest way to fail the mission.
- If you get stuck on an objective, check the surroundings: some targets only appear after interacting with devices near the marker.
- Plan your escape route before completing the last objective: knowing where extraction is, you cut the path instead of improvising on the spot.
What to do if you fail extraction
Missing extraction does not wipe mission progress on every route: on some entries, the zone closes and you must restart the objective sequence. On others, you return straight to the collection point. The rule is the same in both cases: review your stock before re-entering — without healing and ammo, the second attempt ends like the first.
Loadout by mission phase
In the collection phase, the essential item is the suppressor: samples and documents sit in rooms with few enemies, and silent takedowns keep the whole patrol from coming after you. In the elimination phase, the highest damage-per-shot weapon matters more than fire rate — targets are specific and ammo is finite. In extraction, the deciding resource is healing: bring your best healing kit exclusively for the final stretch.
If inventory is tight, prioritize in this order: healing, primary weapon ammo, access tools (if the mission requires them) and only then secondary items. Many players lose the mission carrying useless loot instead of ammo. The rule holds for every phase: each inventory item must justify the space it takes.
Mistakes that cost you extraction
- Drawing attention before the marker: every mistimed fight pulls reinforcements that end up between you and the exit.
- Spending all healing before the escape: extraction is the most dangerous stretch — reaching it with no resources is handing over the mission.
- Ignoring the radio warning: when the area closes, the way back changes — whoever ignores the warning gets cornered.
- Saving your best gear “for the next mission”: Modern Prometheus is hard enough to demand the best you have.
Frequently asked questions
- Can I abandon the mission halfway? It depends on the chosen route — on some entries, the zone closes and extraction becomes the only way out.
- Are secondary items mandatory? No, but they grant progression bonuses and extra rewards at the end of the mission.
- Does the mission have a time limit? There is no explicit timer, but areas can be closed by radio warnings — pace matters.
- Can the mission be done in a group? Yes, and a group makes cover much easier in combat areas.
