Does anybody know any free MMO games to play?

Be on the lookout for Corepunk. I'm very hyped for it. It plays like a MOBA and has battlefog and everything, also the map is one huge map with no loading zones (according to the developers)

It's still in beta. You can sign up for beta from here: https://corepunk.com/en/

Don't be too hopeful though, because I signed up almost 2 years ago and still haven't heard anything from them.
