"Disorder" SEA release is very closed to the official release. Unfortunately, due to the 2019-ncov (virus) situation, the game development has been delayed, and the release time has been pushed to March 20th. Here is the original words from official website:

"Soldiers, due to the severe epidemic brought by 2019-ncov, the development of our game has been hampered.
We are sorry to announce that the SEA release of Disorder has been delayed to March 20th. 
We will try our best to provide you with an exciting game and thank you very much for your understanding."

Wish the dev team all the best.
