Finally, a defect of DSTWO paper box had been found out by a smart customer. He found out that in the box appear two times "Real Time Save" instead of "Real time Save" and "Free Cheat" as shown in the photos from the official website.
Actually, we just noticed this mistake half month ago. And new paper box will be correct.
As you know, DSTWO released for about a year, nobody notice this mistake printed on the box. :)
