Recently, HypeCP changed their original site, HypeCP.Sytes.net from the message left by Connor and Inject, to a game screen which said “Test Server” above. Here is an image.
Although the game is online, there is not a register page. However this “Test Server” could lead to an exciting new development, and you can also have the option to play the original version.
Update: iCPPS.com is now working, however it only shows a blank screen.
