loot based?

[water]

Is this loot based like the division with many many different varients of all the guns?

[Phillium!]

No. The game is going for realism. If you shoot an enemy in the head with anything, they're going down no matter what gun you use. There may be different varients of the guns, but they won't vary dammage wise.

Basically, you can pick-up weapons dropped from the enemies, but each guns won't have variants of their "stats" per say. It will be more around customization like most action shooters out there : You'll be able to change parts of the guns (currently more than 50 guns are said to be included) and its skin. The stats will changes based on the parts, but you won't have 2 identical gun models & parts with different stats.
