Valve's director, Gabe Newell, named Portal 2 the best game of the studio's lifetime. Whether she will succeed this time, or the AI will now turn out to be a triumphant, depends on the actions of the player himself. Artificial intelligence will put a spoke in the wheels of the main character, in every possible way preventing her from achieving her goal - to stop GLaDOS forever. Moving around the scientific complex will be carried out using a special hand-held device that opens small portals - passages between the space.

This time, she will again face the same trials that almost killed her the first time. The girl managed to stop the raging cybernetic creature, but through negligence, GLaDOS was restored by her. A girl named Chell, defeated a powerful artificial intelligence that got out of control and destroyed the entire staff of the Aperture Science research complex.
