Для 100% рейтинга в каждой миссии необходимо выполнить несколько требований, так вот, не обязательно выполнять их за ОДНО прохождение. Уже выполненные требования сохраняются, т.е являются накопительными, что СУЩЕСТВЕННО облегчает получение 100% рейтинга.

Главное во время миссий не пользоваться такси, так как не смогут считать время мисси, соответственно процентное прохождение миссии не зачтут.
