Not to be confused with Elite Crasher, a Boss that is essentially an even larger Crasher with more cannons/barrels/weapons on it, or the Shiny Sentry, the rare variant of the Sentry.

Sentries are Crasher-based entities. They are the main ammunition of Elite Spawners and can spawn within the Pentagon Nest in Old Dreadnoughts and as part of waves in Siege. They are stronger than Crashers and has 3 variants, each with different weapons.

Design[]

Sentries normally are a pink triangle, like Crashers, except they are larger and tougher. They spawn in 3 variants:

  • Swarm Sentry: A Swarm Sentry has a Crasher Spawner shaped like a trapezoid on its back.
  • Gun Sentry: A Gun Sentry has a Mega-3 Turret on its body.
  • Trap Sentry: A Trap Sentry has a Launcher Turret on its body.

Technical[]

Sentries uncommonly spawn in the Pentagon Nest, serving as enemies along with Crashers. They have a good amount of shield, health, and very high body damage, but slow movement speed.

Some weapons have farther FoV than the Sentries themselves, on which they will only begin approaching players within a shorter range.

Sentries stop chasing their targets if they disappear from their FoV or hide behind Maze walls. Sentries collide with other Polygons, and like Crashers, will instantly vanish upon colliding with Maze walls.

In Siege, Sentries only spawn during the start of each wave, with varying amounts randomly spawning from the red Bases. They begin moving onto the center, often starting to target players upon reaching the red barrier. However, they will prioritize attacking Sanctuaries once they enter their FoV, and will commit suicide by ramming into them. Sentries have higher health in this game mode.

Strategy[]

  • Strong Against: Tanks caught in surprise, tanks with melee-based build (Unless the Sentry has been damaged).
  • Weak Against: Bullet spammers, Pounder classes, and high DPS tanks.

Against the Sentries[]

Since Sentries have high shield and weapon stats, players are recommended to attack Sentries with bullet spammers/high DPS tanks like the Twin branch, the Minigun branch, the Sprayer, or the Pounder branch (they easily shred through the shield and HP). Sniper classes are also useful due to the bullet knockback and the Sentry's slow movement speed, as well as their small FoV.

Using ramming strategies is not recommended due to the Sentries' high shield and health stats, which potentially overpower almost any maxed out ramming builds, unless the Sentry is low on health. Tip: Don't ram into the Sentry even if you are a smasher!

Trivia[]

  • Sentries look like large Crashers with some small weapons.
  • The Trap Sentry's turret is bugged in the Private Server Template, as it doesn't shoot.
  • Previously, the Trap Sentry's turret only pointed backwards behind the Sentry and couldn't swivel. This was changed in an update.
  • The Swarm Sentry greatly resembles a mini version of a Guardian from the original Diep.io, with the only difference having an inverted spawner.
    • The rare version resembles it as well, now only having a green body instead of pink.
    • It used to be called a “Guardian Lite,” before more variants were added.
  • Minion versions of the Sentries are used by the Elite Spawner as one of its attacks.
    • The Elite Legions spawn massive versions of these minions as well.
  • Like Crashers, they used to be able to go through walls in older versions. This was removed in an update.
  • Sentries act similar to the Sentinel.
  • Before the new shape system was implemented to the main game, Sentries existed in the main game, aswell as the Crashers and the old shape system. They became exclusive to Siege (and Old Dreadnoughts) after the new shape system was implemented to the main game.
