Apex, Quake Champions, Quake Live, Diabotical, Unreal Tournament (the new one before the team left it for Fortnite) I used to play MMOs heavy before but the grind got to be too much for me so i switched to shooters.
I played this when it first dropped. Love the game but once they changed the map too much, I just didn't like it anymore. I couldn't keep playing it. Always had to rock Lifeline!
