First you need to download and install the Victus Client from :

You need the server files/and client update from:

Download Xampp or any Apache server. You can also use IIS if you want or know how too.

First you need to set it up as if it were any other server. Then you need to install your webserver, or if you already have 1, place UserAuthentication.php in the htdocs/wwroot(I think it is called) folder. Make sure all SQL connections, and setting are properly set in your webserver.
Then we have to edit the hosts file. Add "Your IP auth.gamescampus.co.jp".
This is where a lot of trouble came for me. We have to hex the Account.exe. It has an IP address in it, we have to edit it to whatever IP you are going to be using. It is not md5 or anything like that. We will search for UserAuthentication.php. This will put us within a few lines of the IP we need to edit as seen here. Click image for larger version.

Now we can go on to replacing the files in the client. Just copy and paste it over to the victus client.
Make an account, and log in.
For those of you who want to try to do all the edits from the untouched files, remember to edit UserAuthentication.asp to UserAuthentication.php. Just use a hex editor and search the same way you did looking for the IP. The client is a different encryption, so you have to edit it. I spent a lot of time working all this out, so do not be a hater on my tut.
The client exe, and shns I included have been restored to default encryption.
Do not change any of the zones. They have been hexed to read certain configs.
Do not change the Account Database name. It MUST be named Account.
The account DB is backed up using SQL 2014 Enterprise.
Yes, I know the ressystem is a mess.
I think that is about it. If you have any issues, just leave a reply. Enjoy.
