Fun multiplayer free PC game

[JackM3]

Hello,
I am here today to ask you what do you guys think are some really fun free steam PC games to play with your friends?
I really love to hang out with my friends and play some games but recently just haven't been able to find anything worth my while. My friends PC isn't very high end but can run some games. Please leave some games you guys would recommend.
Thanks
