Main Quest Overview
The main quest matters because it unlocks a hidden story path, major boss encounters, and the powerful unique spear, Itzpapalotl. Unlike ordinary contracts, this chain requires visiting specific planets, raising faction reputation, recovering quest items, and surviving several dangerous facilities.
The quasimorph main quest begins on Venus, moves through Mars and Mercury, then returns to Mars for its climactic confrontation. Prepare before each trip: quest locations can turn formerly neutral factions hostile, and some objectives require extraction rather than simply clearing a map.
| Stage | Location | Main objective | Important result |
|---|---|---|---|
| 1 | Venus | Trigger Xiomara's pact and defeat the Spider Baron | Skull of the Feathered Serpent |
| 2 | Mars, Sinkhole Oasis | Gain access and investigate Realware's hidden facility | Monolith research data |
| 3 | Mercury, Flat Obsidian | Search for the telephaturic dislocator | Broken dislocator parts |
| 4 | Mars, Sinkhole Oasis | Destroy the monolith with a phase bomb | Urparp boss encounter |
| 5 | Mars quest path | Continue the Tezctlan conflict | Itzpapalotl spear progression |
This is a directed questline, but it is still built around Quasimorph's contract structure. You may need to complete regular contracts to raise reputation, acquire supplies, and improve your clone's equipment before attempting the next story objective.
Start the Pact on Venus
Travel to Venus itself, not one of its satellites. Xiomara contacts the PMC when the storyline becomes available and points toward a pact that can oppose Tezctlan.
Take a Venus contract and build Quasimorphosis until it reaches 1,000. This summons the Venus Spider Baron during the rapture phase. Defeating it advances the pact sequence, although a second Venus contract may be necessary if the follow-up dialogue does not trigger after your first kill.
The Spider Baron encounter is more manageable when you control sightlines. Its ranged attacks deal cold damage, which can be dangerous if your armor has poor cold resistance. A corridor or room with one doorway lets you maintain distance and force the boss into a predictable approach.
Use a shotgun loaded with buckshot if you have one. Cut damage is effective, and repeated shots at range can end the fight before the boss can pressure your clone. A character or setup that extends weapon range makes the encounter still safer.
After the boss dies, evacuate successfully. Xiomara grants the Skull of the Feathered Serpent, which appears in ship inventory. Absorb the pact item with a clone to formally continue the story.
| Venus preparation | Why it helps |
|---|---|
| Cold-resistant armor | Reduces the danger from the Spider Baron's ranged cold attacks |
| Shotgun and buckshot | Provides effective cut damage against the boss |
| Open retreat route | Lets you keep distance instead of trading damage |
| Medical supplies | Covers mistakes if the boss catches you in close quarters |
| Reliable extraction plan | The reward is secured only after you leave the mission |
Once the pact is absorbed, Xiomara sends you after Itzpapalotl, a special spear associated with Tezctlan. The next destination is Mars, but access requires more than simply landing there.
Reach Sinkhole Oasis and Find the Monolith
Go to Mars itself and locate the Sinkhole Oasis field camp. Realware controls this camp, and it will not allow access until your reputation with the faction reaches at least 75.
Check faction reputation through the stock exchange interface. Run contracts that benefit Realware until the displayed value reaches the threshold. This is a useful point to stock up, because the camp investigation becomes a hostile operation after you descend into the facility.
At Sinkhole Oasis, do not focus on station cargo. Search for the hidden staircase leading underground. Realware forces below are enemies, even if the faction allowed you to dock at the camp above.
Your goal is the large chamber containing an unusual worm-like monolith. Shooting it does not work. Instead, explore the facility for three monolith research data containers, marked as quest objectives.
| Sinkhole Oasis objective | What to do | What to avoid |
|---|---|---|
| Enter the camp | Reach 75 Realware reputation first | Assuming neutral access continues underground |
| Find the facility | Locate the hidden staircase | Spending the mission searching only for cargo |
| Investigate the monolith | Collect all three research data items | Wasting ammunition on the monolith |
| Leave with evidence | Extract after collecting the data | Overextending with low supplies or damaged gear |
The recovered data reveals that Realware has already tried, and failed, to destroy the monolith through conventional means. Professor Eipschwitz identifies the next lead: a telephaturic dislocator left at Flat Obsidian on Mercury.
Plan for a longer mission before leaving for Mercury. The key item is not located near the entrance, and the search can require descending multiple levels.
Recover the Dislocator and Destroy the Monolith
Travel to the Flat Obsidian field camp on Mercury. The mission plays like a regular facility run, but its objective is different: search deep in the station for the telephaturic dislocator rather than extracting a normal PCPU target.
Descend to level four and inspect the area carefully. The dislocator is destroyed, so collect its three broken parts instead. Extract with them to complete this portion of the investigation.
The failed device leads to a more direct solution. A special phase bomb is placed in ship inventory, and the crafting menu also makes the bomb available as a recipe. Bring a phase bomb back to Sinkhole Oasis on Mars.
Keep the bomb in a vest slot before entering the underground facility. Return to the monolith chamber and use it as you would use a grenade. The phase bomb destroys the monolith and begins the next boss sequence.
Urparp appears after the blast and transports the clone into a separate arena. This boss can be defeated quickly with sustained shotgun fire, but do not treat that as a reason to enter unprepared. Bring enough ammunition, healing, and armor durability for the approach through the facility as well as the fight itself.
A practical route through this part of the quasimorph main quest is:
- Raise Realware reputation to 75 before trying to enter Sinkhole Oasis.
- Collect all three monolith research data items during the first Mars expedition.
- Descend to level four at Flat Obsidian and recover the three broken dislocator parts.
- Return to the ship, equip or craft a phase bomb, and travel back to Mars.
- Use the phase bomb in the monolith chamber.
- Defeat Urparp and follow the subsequent story developments toward Tezctlan and Itzpapalotl.
Keep in mind that contract difficulty is not determined only by the red skull rating. Enemy faction technology, power concentration, facility type, damage resistances, and Quasimorphosis can make a nominally easy mission lethal. Bring gear suited to the faction and location instead of relying on skulls alone.
FAQ
How do I start the quasimorph main quest?
Travel to Venus itself and complete a Venus contract until Quasimorphosis reaches 1,000, causing the Spider Baron to appear. Defeat it, evacuate, and absorb the Skull of the Feathered Serpent from ship inventory.
Why can’t I access Sinkhole Oasis?
Sinkhole Oasis requires at least 75 reputation with Realware. Complete contracts that benefit Realware, then check the faction’s reputation value in the stock exchange menu.
Where is the spear in the main quest?
Itzpapalotl is tied to the Mars storyline involving Sinkhole Oasis, the hidden Realware facility, the monolith, Urparp, and the conflict with Tezctlan. Follow the quest prompts after completing the Venus pact.
What should I use against the Venus Spider Baron?
A shotgun with buckshot is a strong choice because its cut damage performs well. Fight from a long corridor or single-door room when possible, and prioritize cold resistance.
What destroys the Mars monolith?
Use the special phase bomb after recovering the broken telephaturic dislocator parts from Flat Obsidian on Mercury. Put the bomb in a vest slot and activate it in the monolith chamber.
