Как все заметили, в библиотеке Steam, помимо Dota 2, есть Dota 2 тест. Тестовый клиент мало чем отличается от основного, два отличия: онлайн и проведение обновлений. Последнее происходит на день раньше, чем обновление основного клиента.
К слову сказать, обновление тестового клиента в ночь со среды на четверг (МСК), а обновление основного происходит в ночь с четверга на пятницу.
