I've got this info so far, the main executable PXStudioRuntimeMMO.exe has the server IP hard coded into it, it leads to 31.209.60.202:18971 The game communicates on the UDP protocol, probably just on this one port. The current version of the game on the other hand uses 2 ports 18971 and 18975 Unfortunately I wasn't able to find the correct protocol, but probably is (at least some part of it) custom, its patterns doesn't match for example RakNET etc. I'm not sure how to get the information client wants to hear from the server. Tried to disassemble the client with Ghidra, but I am kinda clueless about what to search in there.
