Collaborations
Guardians of the Night collaborated with Scissor Seven and Chinese Paladin, creating the limited-time Agents: Seven, Thirteen, Zhao Ling'er, and Long Kui. Other characters from their respective series were also introduced as Guardians. These characters are unavailable in Night Agent.

Shutdown
Following a lawsuit filed by Tecent Games against Hero Entertainment for copyright infringement, alleging that their game Crisis Action plagiarised map designs from CrossFire, which is licensed and published by Tencent Games. On January 20th, 2020, Hero Entertainment was sued for roughly 45,247,900 yuan (70,636,93 USD) after losing the lawsuit. It is speculated that, in an act of retribution, Hero Entertainment shut down Guardians of Night. This speculation is backed by the fact that the message regarding server shutdowns were sent on January 15th, five days before the final ruling.
