Tactical Alert

Tactical Alerts are special Alert missions that feature unique challenges and enemies compared to traditional Alert missions. While Tactical Alerts appear for a limited time like normal alerts, they occupy their own unique mission node within a planet, and disappear only once their designated duration has expired, making them more similar to Events. They were first introduced in Update 14.2.4.

Mechanics
Unlike traditional Alert missions, Tactical Alerts can contain non-standard enemy compositions such as large numbers of advanced units or even multiple instances of boss units that make the opposition deadlier than usual. Additionally, Tactical Alerts can impose restrictions that limits a player's loadout; many feature so-called "Void Sensors" that places a maximum Conclave point limit that restricts players on the type of weapons and equipment they can carry, which forces the player to use underpowered equipment or incomplete loadouts. Other Tactical Alerts may have other types of restrictions, like being able to use only a specific weapon.

Tactical Alerts also do not disappear after a single run; instead, each successful run of a Tactical Alert will grant points that accumulate with each subsequent run. The Tactical Alert is completed after a certain amount of points are acquired, which will then grant players the stated reward.

Additionally, after completion players have the option of running a Stratos Challenge, which is a more difficult version of the completed Tactical Alert with more powerful enemies and even lower Conclave point limits. Completing the Stratos Challenge has similar mechanics to the above, and will grant a Stratos Emblem (also known as a Tactical Specialist Emblem) upon the first completion, with subsequent completions changing the content of the badge each time a challenge is completed.

Trivia

 * The Avalanche Offensive of Update 14.2 functioned very similarly to Tactical Alerts, likely because it was an early test of their implementation.
