This photograph showcases a discarded mech, its old metal surface and rusty parts telling a story of neglect. Dim light filters through the gaps of the dilapidated mech, illuminating the scene. The mech's tires are flattened and deflated, leaving it stranded in a desolate background amidst the ruins of an abandoned factory. The scene is set in a post-apocalyptic world, filled with sci-fi elements that evoke a sense of doom and gloom.

Avoid images with pristine or newly constructed mechs, absence of rust, damaged tires, or lack of a desolate and abandoned factory setting. Ensure that the mech's decrepitude, the dim lighting, the flattened tires, and the overall post-apocalyptic atmosphere are effectively conveyed, while also highlighting the sci-fi elements of the scene.
