My friends and I play it nightly, because it's a good casual FPS and it has many modes, decent progression. Honestly environment destruction is such a powerful mechanic for making games have variability between matches that it makes each feel unique - like a puzzle even at times.
There's not a great deal of free games right now that are capturing our attention, we wanted an FPS this month, and there's been no paid games everyone's been willing to jump on.
Funny enough we're waiting on Arc Raiders to drop which is also a game by the studio behind The Finals.
