ADVENT Sentry (LWOTC)

Back To Main Page | Back To Units Page

The ADVENT Sentry is the first enemy type XCOM will consistently encounter that is unique to the Long War. While only moderately more dangerous in direct combat than the standard Trooper, the Sentry sets itself apart via its enhanced detection radius and specialization in Overwatch. With its base ability Ready For Anything, the Sentry is able to shoot and enter Overwatch in the same turn, granting it remarkable action economy.

Like other ADVENT troop types, the basic Sentry will slowly be phased out in favor of stronger variants as the campaign progresses. The Guardian gains the ability to fire more and deadlier Overwatch shots, and to do so upon any XCOM action. The stronger-still Sentinel can be surprisingly tough to take down, while also gaining an additional option to take on its own turn in the form of a fragmentation grenade.

Tips

• Like most flankable units, they will ideally try to find reasonable cover whenever flanked. This can be taken advantage of if you want to force enemies to move.
• Their detection radius are higher than most trooper variants so it is best to be wary of spots that may hide them such as dark corners in order to not get surprised yourself.
• The main threat of Advent Sentries is their ability to take a shot and then enter overwatch granting them great action economy very early and throughout the rest of the campaign. The best way to mitigate this ability is to have methods that remove overwatch which there are many of. Some examples are flashbangs, Lightning Reflexes, or simply damaging them (this option becomes more limited as the campaign progresses due to their Covering Fire)
