The Last Signal

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 third-person action mystery game titled “The Last Signal,” built with a dark cinematic sci-fi/industrial visual style. Use a Three.js-like 3D scene with a perspective camera following the player from behind at about 6 units distance, a small circular reticle centered on screen, shadows, blue-tinted lighting, fog, and a rainy night atmosphere. The environment is a large square industrial dockyard: dark blue-green ground with scattered puddle-like flat meshes, rows of brown crates at the far side, blocky warehouse/building forms on the sides, faint cyan-lit panels, a black sky, and visible falling rain. The player is James, represented by a simple dark navy/gray upright suit-like character, starting near the front of the dockyard. Use low-poly/simple geometric props plus animated soldier character models for the mercenaries and heavy enemy.

Start on an overlaid title screen with the mission panel at top left reading “SIGNAL LOST” and “PRESS BEGIN TO ENTER THE CASE FILE,” a centered large uppercase title “THE LAST SIGNAL,” subtitle “A CINEMATIC ACTION MYSTERY,” and a cyan button labeled “BEGIN CASE FILE.” Keep the centered reticle and a bottom-right control hint reading “WASD move · mouse look · click shoot · E interact.” Clicking Begin hides the title screen and starts a short phone-call prologue delivered through a bottom-centered dialogue box with a speaker label and NEXT button: Eve says “I found a lead on the case. Going in alone.”, James says “Wait for backup, don't move!”, Eve says “No time!”, then SYSTEM says “Phone cuts to static… Her phone was found abandoned. 2 years later.” After this, begin the playable case.

Mission 1: show the objective “Eliminate the mercenaries. Then find the laptop.” Spawn three soldier mercenaries around the dockyard, each with one hit point. The player can move with WASD, look with the mouse, and shoot using left click; support a touch/mobile FIRE button at bottom right on touch devices, and Space also fires. Shooting raycasts from the camera forward with a short cooldown and damages the targeted soldier; defeated soldiers simply disappear. There is no displayed health, ammo, score, or lives system. Once all three mercenaries are gone, change the objective to “All clear. Press E near the laptop.” Spawn an encrypted laptop near the back of the yard as a dark rectangular device with a cyan glowing screen. When James approaches it and presses E, show a dialogue box labeled “ENCRYPTED AUDIO” with: “Holding her in underground Sector 4. — signal ends.” Press NEXT to continue.

Mission 2: change the objective to “Facility breach: shoot all 3 red security nodes.” Place three bright glowing red security nodes in a row across the facility area. They each take one shot and disappear when destroyed. When all three are destroyed, hide them and update the objective to “Lasers disabled. Press E to call the elevator.” When the player presses E, show an “ELEVATOR” dialogue message: “Laser grid disabled. Elevator unlocked.” Press NEXT to continue.

Mission 3: change the objective to “Vault corridor: defeat the Heavy Elite.” Spawn one soldier-model Heavy Elite boss at the vault corridor/back area with 3 hit points. The player shoots it until it disappears. Then update the objective to “Vault unlocked. Walk to the sealed door and press E.” When the defeated boss is gone and the player is close to the sealed-door area near the back, pressing E should show a dialogue labeled “EVE” with the line “Wait…”. Press NEXT to trigger the ending.

Ending: replace the game view and mission HUD with a full-screen celebratory reveal using a bright pink, yellow, and cyan gradient background, falling multicolored confetti, huge text “HAPPY BIRTHDAY!”, subtitle “The simulation was a surprise all along.”, a tilted framed photo of birthday lights, and a PLAY AGAIN button that reloads/restarts the case. Keep the overall presentation cinematic and mysterious at first: nearly black title screen, cyan HUD borders and highlights, translucent dark dialogue panels, uppercase spaced typography, blue fog, rain, and sparse environmental lighting. Include a responsive interface: desktop hides the circular FIRE button and uses mouse/keyboard, while touch devices display the FIRE button.
