Chell from Portal 2

The image depicts Chell from Portal, a video game character, wearing an orange jumpsuit and carrying a portal gun on her back. She is walking through a white structure resembling the test chambers found in the game. The background is dark, suggesting it's nighttime or indoors, with some lights visible in the distance. This scene is likely from a fan-made event or cosplay photoshoot, given the elaborate setup and attention to detail. Chell's attire and equipment are faithful reproductions of those seen in the game.
