Chests
There are three types of chests you can find in the Dark Zone, and they all house valuable loot for players (although some are better than others).
You have your standard chests that can be opened by anyone at anytime. These normally house lower tier weapons, gear, and useful items. After that you have your Rank Chests. These can only be unlocked by players with the specified Dark Zone rank. The gear found in these chests is usually much better than what you’d find in a standard one, and geared more towards your level rather than being completely random.
The final chest type requires Dark Zone keys. These rare items can be found by killing Elite Named enemies in the Dark Zone or from killing any fellow Agents who have one. They are definitely worth the effort since some t0p-notch gear.
