Description

The Sentry is the first sentry that is spawned by the Engineer. It spawns when the Engineer is at Level 0-2. It does not spawn on the path and instead on a ground spot in the Engineer's sentry placement range. It takes about 1.25 seconds to build the Sentry.

There is a limit of one unit per Engineer when it is at Level 0-2, limiting the amount of Sentries it can spawn.

Appearance

The Sentry is a quadpod device constructed out of metal, colored black and white. It is a sentry that uses a mounted rifle to attack at enemies. It also has a red laser mounted on top.

Strategy

• The Sentry can do well against enemies that appear early on, such as the Slow or Heavy.
• The Sentry does not have hidden detection, meaning you have to either rely on the Engineer for hidden detection or use other towers.
  • Since the Engineer by itself has very low DPS at the levels the Sentry is spawned, other towers like the Minigunner are recommended.
  • It can, however, be used against Lead enemies.
• The Sentry is not affected by any buff or debuff.
• The Sentry will struggle against any enemy with abilities that damage units, because of its low health.
  • For example, if the Fallen King uses its The Foil, the Épée and the Sabre attack, and a Sentry is caught in the attack, it is instantly destroyed.

Trivia

• The Sentry is based on the Sentries created by the Engineer Monkey from the Bloons Tower Defense series.
• The Sentry is also based on the Sentry Gun built by Engineer from Team Fortress 2
