Cyber City

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a browser-based 3D top-down action/contract game titled “Cyber City // Deniable Contractor.” Set it in Memphis, 2026, on a humid Southern night with a dark cyberpunk/retro-urban visual style: nearly black-blue background and fog, cyan and amber interface accents, sparse blocky low-poly city geometry, moonlight, cyan street glow, and a pink anomaly glow. Use an orthographic-like elevated third-person/top-down camera that follows a simple cyan rectangular player avatar, with a glowing cyan ring under the player. Build a 76x76 city grid with dark roads crossing at regular intervals and four named districts: DOWNTOWN in the northwest, RESIDENTIAL in the northeast, INDUSTRIAL in the southwest, and RIVERFRONT in the southeast. Surround the roads with simple block buildings in district-specific muted colors, plus a few visible props such as a house, dumpster, tree, river walls, and four animated blocky pedestrian characters. Add three pink marked anomaly zones as glowing rings with small marker segments, around the city. Include a parked dark red sedan near the starting area; the player can enter/exit it, and while in the vehicle the cyan body is hidden and the sedan follows the player position.

The core loop is five short contracts. At launch, show a large centered dark translucent panel with a thin cyan border and monospace text: “CYBER CITY // DENIABLE CONTRACTOR,” the setting description, and three client buttons. The three selectable clients are AEGIS PRIVATE SECURITY (“Evidence, escorts, sabotage. Clean money, dirty hands.”), FEDERAL CONTAINMENT (“Anomalies, extractions, evidence suppression.”), and RIVER KINGS SYNDICATE (“Packages, tails, favors. Cash up front.”). Choosing a client hides the menu, assigns the current contract, and places a rotating amber target marker in the city. Contracts in sequence are RETRIEVE EVIDENCE, DELIVER PACKAGE, TAIL TARGET, SABOTAGE SITE, and EXTRACT PERSON. The target locations are fixed across the districts: Downtown (-16,-16), Residential (16,-16), Industrial (-16,16), Riverfront (16,16), then a point near (24,0). The player reaches the amber marker and presses E to complete the contract. Each completion pays $450 plus 
00 per later contract, raises the chosen client’s trust by 12 (capped at 100), lowers the other two trusts by 7 (floored at 0), reduces heat by 15, and advances the contract counter. After five contracts, unlock a FINAL MEETING state instead of another client selection.

At the final meeting, pressing E opens a browser prompt asking for the final demand: AEGIS, CONTAINMENT, or SYNDICATE. Accept the first letter case-insensitively; an accepted choice awards 
500, ends the final meeting, marks the player wanted, and displays a message that the chosen demand was made and the player must escape pursuit by continuing to move for 15 seconds. Invalid choices display a refusal toast. Do not invent a combat system beyond the existing shooting/heat interaction: pressing Space or clicking the mouse fires/reports gunfire, adds 12 heat, makes the player wanted above 35 heat, and shows “Gunfire reported. Patrol response increasing.” Heat naturally falls over time, and when wanted heat falls below 20, clear the wanted state with a “Patrols lost your trail” message. There are no visible enemies or police agents implemented.

Add anomaly documentation: pressing F documents a nearby marked anomaly only when within about 3 world units, awarding 
50, adding 25 anomaly heat and 6 normal heat, and showing “Lemurian anomaly documented. Bonus +
50. Something noticed.” If no anomaly is near, show “No marked anomaly in range.” Anomaly heat gradually decays and the HUD labels the phone camera READY, changing to DANGER above 70 anomaly heat. Pressing E when no contract is active should tell the player to choose a client terminal; E near the car toggles entering/exiting it; otherwise show a nothing-to-interact message.

Use a fixed HUD over the 3D scene. In the upper left, show a dark translucent bordered panel with cyan district title “CYBER CITY // [CURRENT DISTRICT]”, cash beginning at 
200, HEAT percentage, trust values labeled “TRUST AEG,” “CON,” and “RIV,” and “CONTRACT 1/5” through “5/5,” followed by “FINAL” in the final state. In the upper right, show the current mission, initially “NO CONTRACT / Pick a client in the terminal,” then the active client and job type with “Reach the amber marker and press E,” and finally “FINAL MEETING / Choose a demand — then escape the pursuit.” In the bottom right show “PHONE CAM: READY” or “DANGER” and “ANOMALY HEAT.” In the bottom left show the controls: “WASD / arrows move · E enter/exit & interact · mouse aim · click shoot · F document anomaly.” In the bottom center show contextual help such as choosing a client, reaching the amber marker, or choosing the next client. Center-screen notifications should appear as short-lived dark bordered cyan panels.

Implement movement with WASD/arrow controls using an elevated top-down camera following the player, with collisions against city buildings, shadows, fog, directional moonlight, hemisphere light, cyan point lighting, and pink anomaly point lighting. Use monospace typography, dark navy translucent panels, thin cyan borders, cyan headings, amber objectives and client names, red anomaly danger text, and a compact tactical cyberpunk presentation. Ensure the interface is responsive: on narrow screens stack the top HUD and make the client buttons one column, while keeping the game playable in the browser.
