Gorodskie Ekho — The Echo — is a hub supplement for Operator Tactics: Terra Conflictus · 2066. It works as a complete campaign setting or as a drop-in city for existing campaigns. Six fully detailed districts, four factions in active conflict, two escalation tracks, eleven key NPCs, a four-arc campaign structure, and one standalone mission scenario. Everything connects. Nothing is stable.

The city is already in motion when operators arrive. The Syndicate is consolidating. The floodwaters are rising. Someone in The Spire is building immortality from stolen consciousness files. The Soak's four million unregistered residents are running out of time. Operators can work any faction, any side, or none. The city doesn't care. It's drowning regardless.

Gorodskie Ekho sprawls across 47 vertical kilometers of rearranged architecture — a megacity inverted by the Upheaval rather than designed for its current form. The pre-catastrophe street level now sits 40 feet underwater in perpetual twilight, flooded boat lanes threading between submerged corporate arcology and pre-automation infrastructure. Upper floors became ground level. Clean, lit, controlled.

The vertical stratification is absolute. Altitude determines access to breathable air, clean water, and Syndicate approval. The city operates under contested control between the Syndicate (entrenched in The Dry), the Eurasian Oligarchy (claiming territorial authority), and the North American Federation (running covert ops through The Undermap). The Soak's population — swollen with climate refugees and pre-Upheaval underclasses — survives on bootleg tech, community agriculture, and analog black markets. Pressure is rising. The floodwaters are rising faster than the pumps can manage. Something old is waking under the water.

Each district has a function, a controller, a pressure, and a breaking point. None of them are static. Run the day/night split to establish rhythm. Roll encounters to keep operators off-balance. Let the rumors seed future missions. When a district destabilizes, the ripple hits everything adjacent.

Four factions are operating in The Echo simultaneously. None of them have complete information. All of them are making moves the others don't know about. Operators who understand the fault lines between them have tools. Operators who ignore the fault lines get caught in them.

Two escalation tracks are running simultaneously. They operate independently and interact when both reach critical levels. Operators can slow or accelerate either track through their actions. The GM should advance tracks based on time passed in-world, not sessions played.

Track 1 — Syndicate Consolidation & Research Acceleration

Baroness Volstok is moving toward completing her posthuman enhancement program and establishing uncontested control over The Echo.

Track 2 — Rising Floodwaters & Infrastructure Collapse

The water levels in The Soak are rising faster than systems can manage. Pre-Upheaval pump systems are failing. The underlying catastrophe is environmental, not political.

Eleven key NPCs. Each has a drive, a lie they tell themselves, a truth they can't face, and a secret that recontextualizes them when operators learn it. The drives and lies are playable from session one. The secrets are earned. Run them as people first and plot functions second.

Supporting Cast

A Dynasty corporation is hosting a philanthropic gala at the Verdana Tower mid-Current level — climate-controlled, catered, the kind of clean that the Soak only smells from the outside. The Syndicate uses Dynasty charity accounts to move operational funds. Detective Chen has been tracking the discrepancy for six weeks. She needs the raw biometric data from the account-access nodes during the pledge period tonight. She can't pull this herself. She needs the crew.

What Chen doesn't know: Thane has been monitoring Dynasty accounts for weeks. He doesn't care about the financial data. He wants to see who comes for it, who they run back to, and who feeds them dinners when the job is done. He already knows about Maya's kitchen. Tonight he's running parallel surveillance, and the crew is his search term.

The City as Pressure, Not Setting

Gorodskie Ekho works best when it's doing something to the operators rather than existing around them. The districts aren't backdrops — they're systems with breaking points. When operators act in one district, it ripples into adjacent ones. When they make faction enemies, those enemies show up in unexpected places. The city has more going on than any crew can manage at once. That's the point.

Use the escalation tracks as background physics. Advance them based on time passed in-world, not on whether the crew addressed them. They don't stop because the crew is busy. The city doesn't wait.

Dropping In

Any individual district works as a standalone location for an existing OT campaign. Signal Reach is a black market that fits any city. The Lockworks is a neutral faction space that generates its own encounters. The Drift Canal is a transit challenge with multiple checkpoint layers. Each district entry is self-contained enough to drop without the surrounding campaign architecture.

The mission — The Kitchen Job — works as a standalone one-shot or campaign opener. It requires no prior knowledge of The Echo. The crew is given a job, runs it, succeeds, and doesn't realize what they've set in motion. That's a complete session. What comes after is the campaign.

Thane as Antagonist vs. Tragic Figure

Thane's effectiveness as an antagonist depends on the crew encountering him as wrong before they encounter him as dangerous. The dinner scene in Arc 1 — where Maya sits across from something that looks exactly like a person but moves one beat off — is the most important scene in the campaign. If it lands, every subsequent Thane encounter carries that original wrongness. If it doesn't land, he becomes a villain with an unusual method. The difference is in how you play the dinner. He's not threatening. He's lonely. He's trying very hard to feel something that used to come naturally. That's what makes him frightening.

The Flood as Character

The flooding is not backdrop. It changes the map. Sections of The Undermap that were passable in session one may be impassable by session four. Districts that had dry ground level have knee-deep water. Checkpoints that were on stable surfaces are now on improvised platforms. Track water-level changes between sessions and describe them at the top of each session before anything else. The city is visibly drowning. The crew sees it happening and has to decide whether that's their problem.

The Null Collective

Left deliberately blank. If the campaign extends beyond four arcs, the Null Collective is the next layer — a faction whose ideology parallels Thane's work in ways he doesn't understand, and who has been patient enough to wait for him to prove their thesis before they act. What they want with a city full of consciousness transfer data and a rising flood is the GM's question to answer. The Echo has that question. The answer is somewhere in The Undermap.
