I was playing a space arcade shooter https://moonbreakers.com/ and tried to see some of the JS and shader code. However, I was unable to find anything but some server communication code. Game code is thus probably run on servers, but the shaders should at least be local, right? And I have understood that even if the server runs the true game state, clients commonly do some physics interpolation etc by themselves.
My only guess is that the game gets the code with jQuery and it doesn't show in the page source. Can that code be looked at via a debugger?
