Basement Breach

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 playable first-person 3D horror exploration game titled “Basement Breach,” set in a dark underground industrial corridor labeled “Basement Facility B-13.” The player is an army/soldier character seen through a first-person camera, with blocky visible green-clad arms, gloves, legs and boots; the right hand carries a small lantern. Build a long enclosed concrete/metal facility corridor extending from roughly z=8 to an escape wall around z=-34, with dark gray side walls, a low ceiling, nearly black floor, subtle yellow floor stripe segments, diagonal ceiling pipe details, weak blue utility lights, heavy darkness and blue-black fog. Include a warm light near the far escape door. Use a low-poly/procedural 3D style with loaded stylized models where available: factory doors, lantern, key, bookshelf, zombie/anomaly, soldier reference, and shotgun props. The overall visual mood should be extremely dark, sparse, cold, and claustrophobic, with the lantern and occasional flashes providing the main readable light.

Core objective and progression: start near the back of the facility with the HUD objective “Find the key and escape the basement facility.” A jammed factory door blocks the corridor around the early section. Looking toward it and pressing E triggers a roughly 4.8-second first-person break-door sequence: the lantern lowers/disappears, the player kicks, the door vanishes into about twelve tumbling fragments with crash audio, fists rise, a sigh/message appears, and the lantern returns; afterward the door path is clear. Farther down, provide an office door that opens with E and swings aside. Place a rotating collectible basement key in the deeper area around the right side near z=-23.7; pressing E while facing it picks it up, hides the model, changes the HUD from “Key: missing” to “Key: found,” and plays a pickup sound. On the left at the same depth, place a large bookshelf. Pressing E pushes it sideways with a crash, revealing a low, tight crawl opening/vent; show the prompt that the player can crouch near the opening to crawl. Holding C (or the on-screen C button) lowers the camera and lantern, slows movement, and lets the player enter a narrow crawlspace with a very low ceiling; display a crawlspace warning prompt and keep the player constrained inside the tunnel.

Place a locked escape door at the far end around z=-33.7. If the player has no key, E should display “Locked. The key is somewhere deeper in the basement.” Once the key is carried, the first E unlocks/opens the escape door with a creak and the next E begins the ending. The ending should be a sequence of on-screen messages rather than a new playable level: opening the exit, hearing “H-Help... Player...,” a dropped lighter/fire moment, a roar/crash while kicking free and slamming the door, a van stopping outside, and “Hello? Why did you stop?” Finally fade fully to black with white text such as “Thank you for playing. / Child drawings slide by in the dark... / Chapter 2 Coming Soon.”

Add a zombie-like anomaly monster initially positioned deep in the facility. It wakes when the player reaches the deeper area (z < -16) or breaks the jammed door, roars, then uses walk/run animation while pursuing the player through the corridor. It should move toward the player at about 1.35 speed in normal spaces and more slowly in the crawlspace. If it reaches within about 1.1 units, start a 3.2-second jumpscare: roar, shake the camera and thrust the visible arms, show a message that it grabs the player in the crawlspace/screen goes black, then fade to the same Chapter 2 ending text. The player can detect and stun it using the camera flash: the player has a camera available from the beginning, and pressing F or the circular on-screen camera button produces a bright short white flash, camera-in-hands visual, flash sound, and a 2.6-second cooldown. If the anomaly is within about 10 units and in front of the player, display “ANOMALIE Detected!”, roar and stun it for about 3 seconds with a hit reaction; otherwise display “Flash fired.” Do not add guns or shooting as a gameplay mechanic; the shotgun is only a hidden/pocket/reference prop.

Controls: WASD or arrow keys move; Shift runs faster and produces stronger body bob and footsteps; mouse drag/pointer lock looks around; on touch, provide a virtual left joystick for movement and touch look. Click/tap should request pointer lock where possible and toggle the lantern; Space also toggles the lantern. Lantern toggling must visibly change the right-hand lantern state and its point-light intensity, with click/switch audio and brief “Lantern on.” or “Lantern off.” feedback. E or the circular E button interacts with the nearest object being faced: door, key, bookshelf, or escape door. C or the circular C button crouches/crawls. F or the camera button flashes. Apply collision against the facility walls, closed doors, and boundaries, while allowing the broken/open routes through.

HUD and presentation: render a centered small glowing “+” crosshair. At the top center show an outlined dark translucent panel reading “BASEMENT FACILITY B-13” (or “Tight Crawlspace” while crawling). At the upper left show a compact dark translucent status panel with three lines: “Lantern: off/on,” “Key: missing/found,” and “Camera: ready” or its cooldown seconds. At the lower center show a translucent bordered prompt/objective panel whose text changes contextually, such as the objective, “Press E: try the jammed door,” “Press E: take basement key,” “Press E: push bookshelf sideways,” “Press E: unlock / escape,” and the crawlspace warning. Put a large translucent virtual joystick at bottom left with a pale inner nub, and three outlined circular controls on the lower right: camera/flash above, E at lower-left, and C at lower-right. Use pale blue-white typography, thin gray-blue borders, translucent black panels, restrained glow, and no bright ambient illumination. Include procedural atmospheric audio: low drone ambience, footsteps that differ when running, lantern switch clicks/tones, door creaks, crash, sigh, roar, camera flash, and key chimes. Support a black fade for death and ending states.
