Mid-Game Progression Guide
Mid-game SCP Architect X begins when a single-floor Safe-class operation runs autonomously but growth stalls without research investments, wilderness capture, and advanced staff composition. This guide bridges beginner stability and late-game optimization: when to unlock Euclid protocols, how to structure multi-floor wings, where server racks fit profit math, and how to prevent cascading breaches while expanding.
Research Priorities and Budgeting
Mid-game research stops being linear. Multiple Floors (~$22k range historically) unlocks vertical expansion but doubles amenity and security overhead. Euclid research (~$40k tier) opens capture and containment options with higher payouts and higher breach penalties. Sequence matters: stabilize ground-floor bonuses, then floors, then Euclid infrastructure unless events discount specific nodes.
Use the research progression guide and planner tool to simulate orders before committing cash. Overdrafting research leaves you unable to hire security during riot events—a common mid-game failure mode. Maintain a liquid cash buffer equal to at least one week of staff wages at your current headcount.
Server rack research and placements enter mid-game profit calculations via intel bonuses capping around meaningful multipliers when paired with high cleanliness and safety scores. Do not spam racks before bonus averages are green; racks multiply weak bases modestly.
Euclid Wings and Wilderness Capture
Euclid SCPs require wilderness capture missions outside your facility core. Unlock capture gear via research, assign qualified staff, and route captured entities through holding cells before connecting test chambers. Failed capture attempts waste time and cash—read the Euclid capture guide for squad composition.
Design dedicated Euclid wings isolated by security checkpoints and rapid-response staff quarters. Mixing early Safe SCPs in the same hallway as volatile Euclid entities increases chain breach length. Multi-floor layouts should place Euclid floors near task force spawn points if unlocked.
Income scaling improves substantially with well-run Euclid tests, but maintenance costs rise. Track per-SCP profit using tier list rankings rather than hype from launch trailers—balance patches reorder winners frequently during beta.
Staff Composition and NPC Needs
Mid-game hiring expands beyond one scientist and one Class-D. Doctors stabilize health bonuses; maintenance keeps cleanliness; security and task force mitigate riots. Each role consumes amenities bandwidth under NPC needs beta rules—expand cafeterias and restrooms proportionally, not just headcount.
Rotate understaffed wings before bonuses collapse. Foundation UI averages hide localized problems; inspect individuals when bathroom or hunger meters yellow on one floor while others look fine. Medbay stations justify their tile cost once Class-D counts exceed early-game pairs.
Connect SCP desks with redundancy: duplicate scientist desks only when pathfinding confirms both stay utilized. Idle duplicated staff drain wages without additive tests.
Scaling Income Without Overextending
Mid-game players chase SCP count; optimized players chase bonus multipliers and test uptime. Upgrade furnishings that boost cleanliness and safety before adding marginal SCPs with low tier rankings. Consult SCP income and research priority tier lists monthly during beta.
Consider x2 Testing Profits gamepass ROI once net income exceeds the pass cost within a few sessions of active play—never buy during the first hour. Codes and events may inject cash spikes; avoid interpreting temporary wealth as sustainable scaling permission.
Prepare for late-game by documenting layout blueprints and research timestamps. Mid-game is the pivot where disciplined players surge ahead and overbuilders stall under wage and amenity debt.
Frequently Asked Questions
When should I unlock Multiple Floors?
Unlock when ground-floor bonuses stay green autonomously and you have cash for duplicated amenities on a second floor.
Are Euclid SCPs worth the breach risk?
Yes with dedicated wings and security. Without isolation, Euclid payouts rarely compensate for downtime from breaches.
How many server racks should I build?
Follow the server rack profit guide; typically mid-game players place racks after bonus averages are strong, not before.
What stalls mid-game progress most often?
Under-researched security, ignored NPC needs, and copying layouts without understanding connection and bonus mechanics.
