Multiplayer using Steam

So I’m following this tutorial: https://www.youtube.com/watch?v=ABWgSq5A9ak&index=21&list=WL&user=Nsomnia but I’m already running into problem only 10 minutes in. After editing the “DefaultEngine.ini” file, i should be able to Shift-Tab out of the game but it doesn’t work. I first thought it was probably just a typo, but after reading through the file multiple times, and after copy-pasting the problem was still occuring. So I decided to download his project from his site but it STILL didn’t work. Any Suggestions?

Use this to setup steam, and beware that guide does not work, i went through it a few days ago, at the end even his project in the video doesn’t work and just does random things that he doesn’t fix at all, so you download his files to see it better and that doesn’t work at all

You need to have steam open, and select play as standalone in the editor. to make this work when making a shipping build, you need c++.
I heard epic games mention during a live stream that they have recorded a tutorial series for steam intergration, but it still has`nt come up on their youtube channel.
