How to get the Security Clearance Exo Frame upgrade in Destiny 2

Destiny 2’s Season of the Seraph brought players a new Exotic quest that borrows heavily from the Deep Stone Crypt mechanics and scenery, bringing the guardians aboard an orbital platform above Earth. In true Destiny fashion, there are plenty of enemies to fight against—and plenty of loot for the more adventurous guardians to chase.

In addition to the loot at the end of a clear, Operation: Seraph’s Shield also has a slew of secret rooms protected by locks or lasers. Some of these are required to unlock all Revision Zero Security Drones, while others could just yield some extra loot.

The Exo Frame seasonal vendor shows three categories of upgrades: focusing upgrades, efficiency upgrades, and Infiltrator Gear. The first two are the garden-variety seasonal vendor upgrades players are used to by now, with seven upgrades each. The latter only contains three upgrades, but they are key to making the most out of the secrets aboard the Seraph Station.

The infiltrator gear upgrades give players several boons on Heist Battlegrounds and Operation: Seraph’s Shield. Tactical Armor lets them take less damage from lasers and other traps, while the Security Clearance Exo Frame upgrade allows them to open locked doors in both activities. Here’s how you can get the Security Clearance upgrade and discover the hidden secrets aboard the Seraph Station.

How to unlock the Security Clearance Exo Frame upgrade in Destiny 2

The Security Clearance upgrade will first be available for players starting on step 26 of More Than A Weapon, which is equivalent to the fourth week of the seasonal story. Once you talk to Clovis Bray on the Exo Frame, the vendor will allow you to choose one of the three Infiltrator Gear upgrades free of charge.

The Security Clearance is one of the three possible choices early on, and it allows players to bypass locked doors in both Operation: Seraph’s Shield and Heist Battlegrounds missions. The other two choices are also useful in their own way, though both Tactical Armor and Extreme Ordnance can be bypassed or made redundant.

If you miss your first shot at obtaining the Security Clearance Exo Frame upgrade on the equivalent of the fourth week, odds are you’ll have more chances of unlocking it in subsequent weeks, which should be enough to make the remainder of the season easier when it comes to doing Heist Battlegrounds and Operation: Seraph’s Shield.
