SCP Architect X Anomalies Overview

In SCP Architect X, anomalies—based on the SCP Foundation universe—are your primary revenue engines. You contain them, connect them to research infrastructure, assign Class-D test subjects and scientists, and collect per-test payouts that scale into hourly facility income. Anomalies are grouped into three in-game classes: Safe, Euclid, and Keter. Each class differs in purchase or capture cost, research requirements, containment risk, and profit potential. This overview explains how classes interact with progression so you can plan a sane unlock order from your first SCP-005 to late-game Keter captures.

How Anomalies Generate Income

Every anomaly requires at least one Class-D personnel and one scientist to run tests. Place the anomaly in an appropriate containment room, connect it to a research desk using the red triangle laptop mechanic, and ensure pathing from Test Subject Zones and Lab Stations. Tests cycle automatically when staff needs are met, producing gross profit entries visible in Foundation Management under Profit.

Income scales with anomaly tier, staff efficiency, and facility bonuses. Walk distance between inmates and test chambers is a hidden tax on output—tight layouts outperform sprawling campuses even with identical SCP counts. Later systems such as server racks multiply gross profits through Intel bonuses, but only after you already produce strong baseline testing volume.

Safe-Class Anomalies

Safe anomalies are the only class available without research unlocks. They are cheap to purchase directly from the anomaly vendor, easy to contain, and ideal for bootstrapping early cash. SCP-005 ($1,500 purchase) and SCP-999 ($1,000, requires Wilderness capture) are community favorites for first-hour setups. 2026 additions SCP-067 (The Pen and Ink) extend Safe rosters with steady ink-themed tests once your first Lab Station chain runs reliably.

Do not confuse "Safe" with "harmless in multiplayer." Even Safe-class objects can disrupt layouts if desks are unreachable. Stack two or three Safe anomalies before rushing Euclid research so your scientist count and Lab Station footprint keep pace with testing demand.

Euclid-Class Anomalies

Euclid anomalies require the Euclid Class Anomalies research ($40,000, one hour). Most must be captured in the Wilderness using vehicles and containment teams after researching Foundation Transport ($45,000). Prices span from SCP-018 at $20,000 to SCP-008 at $400,000. Humanoid threats like SCP-173, SCP-049, and SCP-347 require active capture missions rather than warehouse purchase.

Euclid is the mid-game backbone: higher per-test income than most Safe objects, but meaningfully higher containment build costs and breach potential if security is thin. Read our Euclid class page and capture guide before buying SCP-087 or SCP-119 without Task Force support.

Keter-Class Anomalies

Keter represents the endgame research gate ($500,000, 1.5 hours). These anomalies are expensive, often captured in the Wilderness, and demand robust security, medical, and maintenance infrastructure. SCP-4636 at $500,000 purchase cost sits at the top of known pricing tables. Keter tests can spike gross profits, but a single breach during under-staffed rioting can erase hours of progress.

Unlock Keter only after Tesla Gates ($100,000 research), strong Task Force coverage from Armories, and stable NPC needs. Keter is a prestige goal, not a rush target for fresh saves.

2026 Anomaly Additions (SCP-067 & SCP-216)

Beta patches in 2026 introduced SCP-067 (The Pen and Ink) and SCP-216 (The Safe) alongside VIP cosmetic bundles and NPC needs tuning. SCP-067 extends Safe-class variety with steady ink-themed research tests ideal after SCP-005 is online. SCP-216 targets mid-game directors who want predictable container income once Euclid infrastructure and security staffing exist.

Dedicated guides cover containment layouts, income tiers, and patch context for each anomaly. Start with patch notes for verified changelog details, then read the SCP-067 and SCP-216 pages before spending code rewards on new wings.

  • SCP-067 — Safe-class ink tests; A-tier filler after SCP-005
  • SCP-216 — Container anomaly; A-tier mid-game with security online
  • Both ship with 2026 VIP pack rollout — cosmetics only, not pay-to-win

Class Comparison at a Glance

Use this mental model when browsing the Profit tab: Safe funds research, Euclid scales revenue, Keter chases peak payouts at peak risk. Always match anomaly count to staff and furnishings—you need parallel Lab Stations and Test Subject Zones, not just expensive SCPs sitting idle in empty cells.

  • Safe — No class research required; buy or capture low-cost anomalies
  • Euclid — Requires $40,000 research; most Wilderness captures; mid-high ROI
  • Keter — Requires $500,000 research; highest costs and containment demand
  • All classes — Minimum 1 Class-D + 1 Scientist per active test chain
  • Connection — Red triangle desk links required for automated research payouts

Multiplayer Sites and Save Slots

Each of the six foundation sites on a server uses the same base terrain but independent save slots—nothing transfers between slots automatically. Anomaly class knowledge still applies: a Safe-heavy Site Director on one slot can experiment on another with Euclid capture practice without risking the main economy. When visiting multiplayer servers, anomaly class tags help guests understand which wings are safe to tour versus which require escort.

Plan class progression per slot, not per account. A creative slot might ignore Keter entirely while a grind slot rushes Foundation Technologies. The class system is flexible enough to support both playstyles if you respect staffing minimums on each save.

Frequently Asked Questions

How many staff do I need per anomaly?

At minimum one Class-D and one scientist per testing chain. Scaling to multiple simultaneous tests requires additional Lab Stations, Test Subject Zones, and scientists—often one pair per anomaly for optimal uptime.

Can I place Euclid SCPs without researching them?

No. Euclid Class Anomalies research must complete first. Captured entities remain unusable until both research and proper containment rooms are ready.

Where do I buy or capture anomalies?

Safe anomalies can be purchased at the anomaly vendor near your site. Euclid and Keter humanoids spawn in the Wilderness tunnel near the Warehouse; capture requires Foundation Transport research and appropriate vehicles or teams.

Which anomaly class should beginners focus on?

Stay on Safe-class until Multiple Floors and Euclid research are funded. SCP-005 and SCP-999 provide gentle learning curves and steady income for early research queues.
