Awesome Allar! But it doesn’t work for me on ubuntu - after login I only get the source response written to console with “web auth failed” (Yes Credentials are correct). Analyzing the response it doesn’t seem to send the required header
'access-control-expose-headers'] == 'X-EPIC-LOGIN-COMPLETE-REDIRECT'
And it would be great to implement the epic provided ■■■■■ from learning tab.
I don’t get it why epic still doesn’t support the linux devs with the launcher 
And the Repo has been renamed:
becomes
npm install -g Allar/ue4-mp-downloader
