I saw the introduction of flood mode on youtube and found it very interesting, but when I played, my delay was always around 600, which made me very distressed. I inquired about the price of my local server, and I would like to fund you a local server with my half month's living expenses (it may not be too good, because it is really too expensive) I'm willing to help you localize the language plug-in (because I only know this, I haven't learned programming)
We have servers located in both EU and US, which can be connected to from their respective IP addresses: us.devinity.org eu.devinity.org When possible, you should connect to the server which yields the better ping for you.
Unfortunately your latency on our servers will be geologically challenged. We don't have a large playerbase established in Asia so it wouldn't make much sense to host another server for that region. Sorry for the inconvenience.
