The newly released Yakuza 6 demo accidentally contained the full game, with a huge error by SEGA allowing players to access all content beyond Chapter 1.
The issue saw players using an undisclosed exploit in order to access the full game beyond the prologue demo, which went some way to explaining why it clocked in at a whopping 36GB. It seems that the exploit was only available in the US version of the demo, and SEGA has now pulled it from the PlayStation Store with the following message:
"We apologize, but have had to remove the Yakuza 6: The Song of Life demo from the PlayStation Store. We are as upset as you are, and had hoped to have this demo available for everyone today. We discovered that some were able to use the demo to unlock the full game. We’re looking into the nature of the issue. Thank you for your patience."
This is a big blunder on SEGA's behalf, and it's unclear whether or not those who figured out the exploit still have access to the full game beyond demo.
In the demo, players could play through its first chapter with their progress carrying over to the main game. However, this exploit allowed them to progress beyond the confines of the demo, and play the full game with trophies activated. It's likely that someone at SEGA will be getting a stern talking-to as a result of this huge mistake.
Yakuza 6 will release on April 17th, 2018, so those who didn't receive the full game as part of today's demo can get their hands on it in in a month and a half.
