Euclid-Class Anomalies in SCP Architect X

Euclid-class anomalies mark the transition from tutorial sandbox to real SCP facility management in SCP Architect X. They require dedicated research, many spawn in the Wilderness, and several humanoid entities demand live capture missions instead of credit-card purchases. Per-test income jumps dramatically compared to most Safe objects, but so do containment footprints, security staffing needs, and breach recovery costs. This guide explains unlock prerequisites, notable Euclid price tiers, and how to integrate them without collapsing your staff happiness systems.

Research and Transport Prerequisites

Start Euclid Class Anomalies research from Foundation Management for $40,000 and a one-hour timer. The research completes offline, so queue it before breaks. Purchasing Euclid entities from vendors or placing captured ones still requires this unlock—research is not optional. Most directors pair Euclid research with Foundation Transport ($45,000, two hours) because Wilderness captures and vehicle purchases at the Warehouse depend on it.

Without transport, you are limited to non-capture Euclid SKUs bought directly—SCP-018, SCP-079, and similar. Capture missions for SCP-173, SCP-049, and SCP-347 remain locked until you can deploy teams beyond the main site.

Euclid Pricing Tiers and Notable SCPs

Lower Euclid entries like SCP-018 ($20,000) and SCP-049 ($25,000 capture) bridge mid-game budgets. SCP-079 ($30,000) appeals to tech-themed sites. Mid tier includes SCP-087 ($50,000), SCP-119 ($55,000), and SCP-173 ($60,000 capture)—community benchmarks for serious income jumps. High tier spans SCP-347 ($85,000 capture), SCP-457 ($90,000), SCP-5293 ($100,000), SCP-5070 ($150,000), and SCP-4854 ($175,000), which tutorial videos highlight as top Profit tab performers.

Ultra tier Euclid anomalies such as SCP-513 ($190,000), SCP-009 ($200,000), SCP-5020 ($300,000), and SCP-008 ($400,000) should never be impulse buys. Fund Tesla Gate research ($100,000) and Task Force Armories before welcoming these objects into populated wings.

Wilderness Capture Overview

The Wilderness sits beyond a tunnel near the Warehouse—a forested zone where anomalies spawn along branching paths. Capture flow typically involves accepting a mission, driving or deploying teams via Offroad Titan after Foundation Transport, securing the entity, and escorting it back. Humanoid SCPs fail captures if security or Task Force staffing is thin. Read our dedicated capture guide for step-by-step riot prevention during transport.

Failed captures waste time and can injure staff, triggering medbay load and Health bonus penalties. Scout with cheaper captures like SCP-999 before attempting SCP-173.

Containment Strategy and Staffing

Euclid cells need redundant doors, observation glass, and proximity to Security Stations or Task Force Armories. Connect desks immediately—unconnected Euclid anomalies are expensive decorations. Scale Test Subject Zones and Lab Stations in parallel; SCP-4854 income means nothing if one scientist serves five anomalies across a sprawling map.

Schedule Tesla Gate placement at choke points after researching the 16-hour Tesla Gate topic. Gates mitigate breach spread during Class-D riots, which spike when testing high-throughput Euclid lines.

Income Planning Across Euclid Tiers

Mid-tier Euclid purchases between $50,000 and $100,000 often define mid-game paychecks. Directors who jump from SCP-005 straight to SCP-008 frequently stall because $400,000 capital sits idle without enough Lab Stations to saturate tests. Instead, stair-step through SCP-018 or SCP-079 bands, reinvesting each paycheck into another Lab Station pair before the next anomaly.

Watch the economics report Gross Profits line when adding each Euclid cell. If gross climbs less than ten percent after a major purchase, your bottleneck is staffing or desk connections—not anomaly tier. Fix operations before buying the next Euclid license.

Building Euclid-Ready Containment Rooms

Euclid cells benefit from airlocks: two doors between corridor and chamber reduce breach spread when tests go wrong. Observation windows let scientists trigger laptops without entering cells—critical for humanoid captures like SCP-173 where line-of-sight mechanics matter in SCP lore and player anxiety.

Pre-build two empty Euclid modules before completing Euclid research so placement begins the moment the timer finishes. Idle research time paired with idle build time doubles mid-game stalls.

Vendor Purchases vs Wilderness Captures

Not every Euclid anomaly requires a Wilderness trip. Vendor-purchasable objects like SCP-018 and SCP-079 let you test Euclid income loops while still learning capture logistics on optional side missions. Humanoid captures should be scheduled events—not impulse detours that drain Task Force when your main site still lacks medbay coverage.

Frequently Asked Questions

How much does Euclid research cost in SCP Architect X?

Euclid Class Anomalies research costs $40,000 and takes one hour. It continues progressing while you are offline.

Which Euclid SCPs must be captured?

Humanoid anomalies including SCP-049, SCP-173, and SCP-347 require Wilderness capture. Objects like SCP-018 and SCP-079 can be purchased without capture missions.

What is the highest-profit Euclid anomaly?

Profit tab rankings shift with updates, but SCP-4854 (~$175,000 cost) frequently appears near the top of community comparisons, followed by other high-tier entries like SCP-5020 and SCP-008.

Can I research Euclid before Multiple Floors?

Yes. Research order is flexible, though most players unlock Multiple Floors ($22,000) first for layout efficiency, then Euclid, then Foundation Transport for captures.

Do Euclid anomalies need Tesla Gates?

Not strictly, but Tesla Gates ($100,000 research, 16 hours) dramatically reduce breach escalation when testing volatile Euclid lines alongside unhappy Class-D personnel.
