How to improve the Beta experience?

[KingOfTheStreets]

So, I've been messing around with the Beta for around a month now. I have Missing Information, is there any way to use it with the Beta? I've watched Valve News Network's Beta stream, and he was using Missing Information to play the Beta, as well as The Axel Project. If the beta is used with these mods, will the experience be more streamlined and overall better, like he did? https://youtu.be/8TBYLwYBy-M

He was not "using Missing Information to play the Beta" whatever that means, he just played a bunch of retail mods. Which is exactly what video description says.
