Make a 3D first-person military shooter in one web page: a lone soldier fights through an abandoned dockside refinery at sunset, with cranes, shipping containers, catwalks and long shadows. WASD to move, mouse to aim, click to fire, right-click to aim down sights, R to reload, Shift to sprint. Give the rifle a red-dot sight, recoil, muzzle flash and a reload animation. Enemy soldiers patrol, take cover and shoot back. Add a HUD with health, ammo, a crosshair, hit markers and a kill counter, plus win and game over screens. Make it look as cinematic as you can. It should feel fun the moment it loads.
