Here's a alternate one step guide to having maximum fun on the CN SCP-RP server.
First, work your way up to level 5, mainly request crediting and always riot when theres no researchers, constantly request credit when available.
Once reaching level 5, switch to the junior researcher, constantly offer credit to guards and cadets who want it even without a test, credit any random d-class, do as many tests, make sure to be unethical as possible without being caught or use loopholes to stay unethical without being unethical, constantly credit d-class, always find ways to avoid execs and look good to them when you're nearby execs.
Then you'll unlock researcher, by this point you can credit anyone with authorization, meaning you can rush your way into airlock and into d-block vents, there you should credit everyone, get a good rep from em, the d-class will like you, again, repeat everything before, be more careful, so and so until you reach....
Sr Researcher, this is your general end goal, what your life will be about first is building a nice doc for 106 sampling and other samples for scps t get unstable liquid reality and stable quantum matter, mix em up, and get yourself NHU, after that you can consume it and go ahead and grab that big ol rocket launcher, go nuts.
