Marathon is a stylishly merciless video game built for cut-throat times

I n rare quiet moments playing Marathon, you may find yourself overcome by the iridiscently pretty planet Tau Ceti IV. This fictional world seems to radiate a chemical glow: powdery pink skies and lurid green vegetation fill the screen alongside supermassive architecture emblazoned with ultra-stylish, neon graphic design. Yet enjoy the scenery for a split second too long and you might catch a bullet, causing your character to bleed an icky blue substance. In such moments, the camera locks - meaning you must stare down at their unceremonious expiry. Marathon's considerable beauty is matched only by its clinical brutality.
