OVERTIME — Office Hell is a free 3D browser FPS with a brilliantly relatable premise: you are working late at the office one more time, and this time the coworkers really are demons. What starts as fluorescent-lit monotony erupts into a full supernatural invasion, and your toolkit is suitably overkill - a pistol for precision, a shotgun for the runners that sprint cubicle-to-cubicle at your face, a machinegun for sustained suppression, and a rocket launcher with splash damage for the brutes that just will not die. The office itself is the star: real 3D workstations, sofas and office plants become cover, sightlines and tactical problems, and the Three.js-powered presentation keeps the FPS smooth in any modern browser. Three demon types force weapon discipline - runners punish slow reflexes at close range, spitters outrange you and reward breaking line of sight, and brutes demand your heaviest ordnance - so survival becomes a moving puzzle of repositioning, ammo management and quick swaps. The viewmodel weapons are fully modeled 3D assets with animation, the horror-comedy tone lands somewhere between Doom and a bad day at work, and every run is a survival score chase: live longer, drop more demons, clock out with dignity. There is no download, no install and no account - click to lock the pointer and start the worst shift of your life. Recommended with a mouse, headphones up, and the lights off. Your inbox can wait; the demons cannot.
