Create a detailed and atmospheric image inspired by the game

Create a detailed and atmospheric image inspired by the game 'Half-Life 2'. Show a post-apocalyptic urban setting, with destroyed buildings and streets covered in invasive vegetation. Add the presence of iconic game elements, with the Combine citadel in the background, and a central figure with HEV armor and a weapon, symbolizing Gordon Freeman. Also include the presence of Combine robots patrolling the area and shadowy lighting., with a cloudy sky and predominant shades of gray and green. The image should capture the feeling of a devastated and oppressive world, typical of the 'Half-Life 2' atmosphere
