Vendors
If you’ve got the cash, vendors are a sure fire way to get yourself some pretty powerful weaponry. While the ones in the Safe Houses and your Base of Operations will net you some great gear, your best bet for purchasing High-End weapons is from Dark Zone vendors. These guys, just like they did in the beta, will have High-End weaponry up for sale but for an equally high price. You’ll need to spend a lot of time in the Dark Zone to get the funds together, but it’s totally worth it.
One thing to note about purchasing High-End weaponry from vendors is that your perks and buffs for these weapons will be the same for every agent. On the other hand, gear looted from chests and fallen enemies can have unique abilities for every single agent. So if you don’t like the stat boosts on offer with the purchasable High-End weapons, your best bet is to start searching Manhattan.
