Iron Horizon

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-playable low-poly 3D tank combat game titled “IRON HORIZON / OPERATION HEDGEROW.” Use a Three.js-style perspective scene with a large square battlefield of muted olive-green meadow strips, dark brown mud strips/hedgerows, a pale gray country lane running roughly through the field, and a crossroad. Add simple blocky low-poly scenery: scattered stylized oak trees made from short brown cylindrical trunks and chunky dark-green cylindrical crowns, three farmhouses (two intact warm orange/brown buildings and one damaged brick-colored building with rubble), a rough wooden fence line, and multiple flat shell craters. Use overcast military colors, strong directional sunlight and soft shadows, atmospheric fog, and a restrained realistic/retro low-poly aesthetic.

The player controls a detailed but blocky olive M4A3 Sherman tank, initially positioned near the foreground/southern side of the map. Build it from a rectangular hull, sloped front glacis, cylindrical turret base, boxy turret, dark mantlet, long dark 75mm barrel and muzzle, black side tracks with six visible road wheels per side, hatches, antenna, rear orange-brown stowage links, and exhaust. The camera supports three selectable views: gunner/first-person near the gun, commander/raised close view, and third-person chase view behind and above the tank; start in third-person. Keep a small circular aiming reticle centered on the screen. The tank can drive forward/backward and steer, with optional faster movement while holding Shift. Keyboard controls: W/S drive, A/D steer, Q/E rotate the turret, Up/Down adjust gun elevation, Space fires, V cycles camera view, R reloads. Also provide visible buttons for FIRE, RELOAD, VIEW, WEATHER, and RESET. On coarse-pointer/mobile devices, show a translucent circular virtual joystick at lower left: vertical input drives and horizontal input steers, with the other actions still available as buttons.

Place exactly three enemy tanks across the battlefield, visually similar but darker gray-green and named/treated as Panzer IV enemies. Put them approximately at (-18,-30), (35,-5), and (-48,32), with varied initial headings. They do not need AI movement or return fire; they are stationary targets. Each begins with 3 hit points. The Sherman carries 7 rounds of 75mm AP. Firing is limited by a roughly 0.9 second cooldown and is blocked while reloading or empty. Spawn a visible small orange shell traveling in the turret’s forward direction; shell impacts count as hits when they come within roughly 4 world units of an enemy. Each hit produces a brief burst of orange impact sparks; after three hits, hide that enemy and award 100 points. Let shells persist only briefly if they miss. Display recoil/camera shake when firing. Reloading takes about 2.4 seconds, refills the ammunition to 7, and shows the message “RELOADING 75MM AP...” during the reload. There is no player damage system: keep the hull integrity readout at 100% and report whether tracks are moving or nominal.

Use a fixed HUD overlay with a military briefing/interface look: top-left gold title “IRON HORIZON / OPERATION HEDGEROW,” top-right dark translucent status panel showing weather, “14:20,” and “RANGE 420m”; centered thin cream circular reticle; and a bottom readout panel showing “M4A3 SHERMAN • 75MM AP,” a large two-digit ammo count starting at “07,” and a line such as “HULL INTEGRITY 100% • TRACKS NOMINAL • SCORE 0.” Along the bottom right, show the action buttons and a help strip reading “WASD drive • mouse aim • Space fire • V view • R weather” (the implementation’s actual turret controls are Q/E and arrow keys, so include those as functional controls as well). Weather cycles through SUNNY, RAIN, and FOG when the WEATHER button is clicked or R is pressed; update the top-right label and alter the scene background/fog density, with the initial presentation in rainy, gray-green conditions. RESET returns the player, turret, ammo, score, and all three enemies to their initial states. Make the interface responsive, preserve the full-screen 3D canvas, and use shadows, fog, muted materials, and block geometry to match the grounded wartime hedgerow screenshot rather than a colorful arcade style.
