好玩！！！！
this is a really good game!
"You always boss me around and you are selfish you haven't sacrificed anything and it's time for me to be in charge". That British MF doesn't know the pain of having to be TESTED TWICE
Графика нравится, сюжет ТОП, загадки ТОП, шутки Гладос замечательны, любое железо потянет (10000000000 порталов из 100). Игра ТОП.
Хорошая Игрушка Хороший сюжет + на долго затягивает в общем рекомендую
Хоть, я и сделал огромный перерыв от Портала 2, из-за того, что хотел сразу поиграть в портал 2, после того как прошёл первый на 100%, но концовка в муражки бросила. Эта песенка от турелик в конце с царь турелькой просто шик. Да и титры, тоже кайф. Да и Уитли в Космосе крутой. Короче, вы поняли. Игра класс, и короткая, и приятная, и кооп есть, который тоже скоро допройду с Mancy. Да и по сути она бесконечная, проходи да проходи с новыми людьми, пока не надоест. Оценку поставить чутка сложновато, но пока 9/10 она просто балдёжная. Так же чёт допишу когда пройду на 100% игру
