There's more to it than just a tactical shoot 'em up situation, but the ability to customize your character's equipment at a mathematical level, according to a report at Lazy Gamer, which lends its appeal to those who appreciate such an advancement. There does appear to be an evolution of character development in The Division game once weapons and gear are discovered on the bodies of fresh kills or in boxes, and then utilized or even customized at a later time for further improvements in the field like in the Dark Zone.
The Division gameplay experience reported by The Lazy Gamer and their corresponding video, gave unto a limited access to player traits when partaking in missions. There does seem to be an initial fortification process of taking over The Post Office as a base of operations. Later, your "first, and only, story mission" to complete involves securing the Medical Wing to achieve one of the three abilities your division agent possesses.
Another part of The Division game is that the AI does keep you on your toes as they take on a more aggressive, tactical stance when firing and maneuvering towards your flanks. In case you do get cold feet after sitting for too long, they come your way and are even reactionary to your own advances, which is pretty remarkable.
Now, enter the Dark Zone. It's a PvP area in the game where everyone is on equal ground. However, there are classifications.
If you're teamed up with your real-life buddies around town or are part of a online clan/squad, you may not have to worry about someone shooting you in the back, but anyone else other than your buddies has potential to shoot you on the spot and rob you. If you're going at it alone, even an extreme risk exists. In fact, it is highly recommended that you team up with someone.
