First, we got the ruby from the art room on the second floor on the west side of the police station. Here we need to get the plum blossom key, open the interrogation room and get the exquisite box. Combine the box with the ruby, and we can get the badge.
Check the badge and find that it is a USB flash drive, and then you can get Shaying in the startup office on the second floor on the east side of the police station. Don't throw away the badge after use. After solving the coin problem, the player goes to the underground of the police station. Here is a demonstration case, players can use the badge again and get the upgraded part of Sha Ying.
Development background:
After the release of Resident Evil, Paul of Sanshang immediately started the development of Resident Evil 2, which is scheduled to be released on March 1997. When the first edition of Resident Evil 2 was 80% completed, Paul was extremely dissatisfied with this version, so Resident Evil 2 was forced to make it again. This rejected first edition was later called Resident Evil 1.5.
Meanwhile, Capcom said Resident Evil 2 will be developed on both Playstation and Sega Saturn platforms. 1998, the final version of Resident Evil 2 was released on the PlayStation platform for the first time and achieved unprecedented success. However, the development of Resident Evil 2 in Sega Saturn was suspended, and it was temporarily sold on the follow-up models of SEGA.
