I find it interesting that they appear to use the GMS client during testing. Always had a weird suspicion that GMS was the "lead" non KMS server but I think this almost???? confirms it.

This is part of their anniversary events incorporating water gun battles between Cygnus Knights and Resistance (something like Cake VS Pie). Meanwhile, ChinaMS was having a real life swimming pool party with regards to this event last month. TWMS is the first who makes this into the official server though.
