At its best, the unpredictable combination of 66 players trying to complete their own objectives, and hostile AI scattered throughout the map, leads to unpredictable, emergent moments of gameplay that afford you a ton of freedom in terms of how you wish to survive, fight, loot, and exfiltrate.
The whole point of the mode is to survive with better loot than you came in with so you can use your fun new toys in future matches.
The premise of the mode itself is difficult, but the hostile AI, however, is making the mode simply fucking miserable and humiliating.
Without a doubt, the aggressiveness of the bots in this mode is simply off the charts, making them far more intimidating than other players.
