Personally I loved being able to team up with a bunch of random strangers and destroy NPCs. It’s a nice change of pace from the Campaign and PvP game modes. I felt that the game mode was sufficiently challenging and balanced, having won maybe 50% of the time. The only problem I had with the whole thing is that my team and I could never beat the ‘Defend the Garage’ wave that sometimes popped up. Otherwise it was a wonderful blend of the new Warzone and time-tested Firefight game modes.
