MHW squad group

"Now, to make is really easy for your friends to be in the same online session, I recommend forming a squad. These are like guilds in other game; you create a squad and invite members to it, and once that is done anyone in the squad can create a squad session which squad members will join if they also select "create / join squad session". For PC, Monster Hunter World uses your Steam Groups as squads. So to create a squad for you and your friends, you need to make a group in steam, then you should be able to hop into squad sessions normally."
