Quasimorph Tezctlan storyline guide: the revivalist military arc, rites & pacts, plus the Unchained Belt (Ship of Ghouls) and Xiomara (Feathered Masks).
Quasimorph Tezctlan Walkthrough — Storyline, Unchained Belt & Xiomara
The Tezctlan storyline follows revisionist military cells fighting cultural extinction across corporate stations — disciplined enemy squads, ritual narrative stakes, and the tightest link to the 142 pacts system in version 1.0 (Steam, July 31, 2026). This guide also covers the two arcs players hunt after the headline five: the Unchained Belt pirate union with its brutal Ship of Ghouls exam, and the cross-faction Xiomara arc with its Feathered Masks and standing traps.
Start with the campaign walkthrough for route order — Tezctlan is a strong second first-playthrough pick once you've certified on Mars.
Here's what you'll learn:
- How to unlock Tezctlan and what makes it a strong second arc
- Rites, pacts, and standing in the revivalist network
- Securing the Tezctlan ending
- Unlocking the Unchained Belt and surviving Ship of Ghouls
- The Xiomara Feathered Masks arc and its multi-faction traps

How to Unlock Tezctlan
Tezctlan opens by selling the starting Secret Data (from the tutorials) to Tezctlan. It's one of the three Data-sold arcs (AnCom, RealWare, Tezctlan). Once routed, revivalist contracts appear on the board.
Tezctlan suits players who want structured military combat with cultural weight. Enemy squads behave more cohesively than Mars bandits — flanking, suppressive fire, and shield lines appear early, so it reads as a difficulty step up from Civil Resistance. It also introduces pact decisions earlier than corporate storylines.
Rites, Pacts, and Standing
Tezctlan missions reference rites — narrative beats that often gate pact offers or faction-standing shifts with revivalist networks and Dilthey-adjacent researchers. At 1.0 launch, 142 pacts span the campaign, and Tezctlan concentrates several high-impact options tied to skull mechanics and long-term clone costs.
Spoiler-light pact rules that matter for Tezctlan:
- Read full pact text before accept. Some benefits expire after N missions while debuffs persist — a permanent handicap for short-term power.
- Pacts can shift barter inventory on the Magnum without a prominent UI banner. Recheck the economy guide barter tables after major rites.
- Corporate pacts accepted during side contracts may conflict with Tezctlan finale standing. Watch the reputation floors explained in the factions guide.
It's easy to stack power pacts mid-arc, but each debuff compounds across later missions. If a rite hands you a choice that trades a permanent clone-stat penalty for an immediate reward, weigh whether your loadout can absorb it through the finale.
Mission Discipline and Horror Pacing
Tezctlan sits beside Civil Resistance as a gentler horror introduction — but that gentleness is relative. It reaches non-Absentia stations, yet Control and Security contracts appear frequently enough to progress without constant Rapture stress. Use meter-locked mission types to advance standing safely, and save assault/loot contracts for beats that actually need horror-active drops. See mission types and the Quasimorphosis survival guide.
The Tezctlan Ending
Tezctlan anchors one primary ending lane within the nine-ending set. It's a state check at the epilogue gate, not a hidden collectible: reach the finale, hold the right standing, extract key quest items, and carry the right pac-based flags. No max reputation with every faction is needed — see the campaign walkthrough ending routing.
Unchained Belt — the Pirate Arc and Ship of Ghouls
The Unchained Belt is the Main Belt pirate union (bases like Hargeysa on Interamnia) — freedom-for-freedom's-sake crews, convoy ambush routes, and their own traders and Class Chips. It sits beside the five headline arcs, and its flagship story mission is the endurance Ship of Ghouls.
How to unlock the Unchained Belt
Community-confirmed unlock for the Belt story mission:
- Drive negative reputation with any three corporations.
- Tezctlan and Civil Resistance standing do not count toward those three corporate hits.
- Wait for the Belt contact / board flag — don't hunt invisible map markers.
Practical loop: accept assault or sabotage contracts that explicitly punish RealWare, AnCom, SBN, Tianmìng, or other corporate tags, bank Magnum purchases first (sub-zero standing clears barter points — see the economy guide), then check the board for the Belt flag.
Belt standing opens pirate-market barter: weapons like the Westside, Crash 17, Raider M16T kits and Corsair / Buccaneer armor sets — distinct from rebel med caches.
Surviving Ship of Ghouls
Ship of Ghouls is an endurance gauntlet, not a short cache run. Community reports cite roughly five-skull pressure and wave densities near 200 quasimorph kills across floors. If you've only cleared Civil Resistance and Tezctlan, don't treat it like another Mars briefing — certify midgame combat first:
- Blunt and mixed damage carry through high-pressure floors better than precision single-shot kits.
- Medkit and ammo reserves matter more than loot. You're surviving wave after wave, not extracting fast.
- Extract when the pressure spikes — staying for one more floor to grab gear is how the run ends.
Endgame combat and the Baron-type pressure overlap with our Baron boss guide.
Treat it like the game checking every midgame habit at once: room clearing, stance switches, ammo discipline, and knowing when to cut losses. Bring a clone you're ready to lose.
Xiomara — the Cross-Faction Feathered Masks Arc
Xiomara is the cross-faction story where Civil Resistance, Dilthey, corporate blocs, and Feathered Masks iconography collide. It's the arc that punishes reputation mistakes most harshly: raising one ally for a contract can lock another ending path three missions later.
Why Xiomara is a second-run arc
Xiomara assumes you understand:
- Barter floors (sub-zero clears points) — economy guide
- Faction territory overlap — factions guide
- Meter-locked mission selection — mission types
- Extract discipline — extraction guide
New players can start it, but the standing knock-on effects feel opaque without prior corporate and rebel context.
Feathered Masks narrative stakes
Feathered Masks imagery marks Xiomara's cultural and espionage layer — masked intermediaries, ritual smuggling, station infiltration. Masks missions often require quest items that must extract alive. Clone death resets more progress here than in Absentia farming because items rarely drop twice on the same board rotation.
Xiomara branch points read multiple reputation values simultaneously. The UI shows current values, not future requirements — screenshot or log standing before each flagged contract, and avoid assault sprees on corporate stations between beats unless the brief mandates it.
Xiomara's late acts converge Feathered Masks threads toward one primary ending lane in the nine-epilogue set.
