Advanced Tester
Welcome back, test subject. This time, your trials will be even more excruciating. Complete the entire game to test your heart—and possibly break it. Conquer advanced maps, because mediocrity is not an option. Defy gravity with impressive jumps and falls that will make even physics cringe. Immerse yourself in the torturous world of Portal for at least 10 hours. Remember, your pain is my entertainment. Enjoy the descent.
