It used to be but became paid (to people who didn't already have it) on it's full release. Honestly a fun game, but almost nobody plays it unfortunately so there is basically only one active lobby at a time while me and a friend were playing
Edit: aside from the fun gameplay, you also get to spam voice lines. WAGGGHHHH
Never tried it before but finally playing Enderal (whole game made with the Skyrim engine basically). It's pretty good so far.
With friends, mostly just The Finals. Still very fun (if you're into competitive multiplayer)
