I'm Thinking of Making a More True to Canon Version of SCP - Containment Breach. Any Tips?

I've heard from a lot of people that SCP - Containment Breach has a lot of aspects that aren't canon. That being said, I'd like to take up the challenge of making a game that is as canon as possible. This could hopefully serve as a way to bring the experience to people who prefer to stick to on-site information and not made-up headcanons. Having said that, I'm relatively new to SCP as a whole, so I have a lot of research ahead of me. So I wanted to know if you guys had any tips or maybe a "Do and Don't List". Thanks for your time. :)
