Arras:Tiers

This page is a Stub. Please help us expand it!

This article is about the Arras.io Tiers. For the original Diep.io equivalent, see Tiers.

Tiers are represented in the Class Tree. It can be displayed in-game by pressing the T key or any key depending on what key bind you've set it to.

There is a recurring pattern of colors in the upgrade selection menu and the Class Tree. The first tank will always have a teal background. The second option will be light green. The third option will be red. The fourth option will be yellow. The fifth option will be purple. The sixth option will be pink. The seventh option will be gray. The eighth option will be dark gray. The ninth option will be white. The last three colors are currently only used by these tanks in order; Trapper, Smasher, and Single. The Musket, when upgrading from the Twin also uses the color gray. The color order can also be found in the tank’s Stat buttons, which are color-reversed compared to the pattern in the class tree. Some colors are just different shades of them, however. Regardless of speculation, these colors do not seem to represent anything other than a simple order pattern to more easily distinguish tanks apart when quickly selecting an upgrade for now.

Tier 1: Level 1

Basic
The tank that the player starts with in Arras.io. The player has one Cannon that can destroy Squares in 5 hits, Triangles in 19, and Pentagons in 48 with no additional Stats. The health, Bullet, and movement statistics are average and can be upgraded as they gain more points upon destroying Polygons and killing other players.

Tier 2: Level 10

Upon reaching Level 10, the player may choose to upgrade to one of these Tier 2 specializations or ignore them to get to the Smasher or Single.

Basic Upgrades

	Twin Choosing the Twin class grants an extra frontal Cannon while Damage and Penetration are slightly reduced.
	Sniper Choosing the Sniper Class lengthens the Cannon a bit, and grants a broader field of view allowing the player to shoot at an advanced distance. Bullet Speed is also increased. However, Reload speed decreases significantly. Damage is not increased.
	Machine Gun Choosing the Machine Gun class turns the Cannon into a trapezoid and allows the player to spray Bullets in a frontal cone. It fires double the rate compared to the Basic—the same rate of the Twin tank. It’s less accurate but it covers a wider area.
	Flank Guard Choosing the Flank Guard class adds two Cannons on the rear. This allows the player to shoot in three directions to defend themselves. Since all Cannons have identical Recoil, the Recoil effect is nullified.
	Director Choosing the Director loses the Cannon, but grants the ability to control a maximum of five drones. It is essentially a downgraded Manager without the power to turn invisible. Bullet Speed, Damage, and Movement Speed are lowered, while Reload is harshly reduced. Although, penetration is increased.
	Pounder Choosing the Pounder increases the size of the Cannon, and amplifies its power. Being a somewhat predecessor to the Destroyer, it boasts high damage and penetration but at the cost of losing bullet speed, and having more recoil and reload time.
	Trapper Choosing the Trapper replaces the Cannon with a Launcher, which discharges stationary 'bullets' called Traps. As this ammunition is shot, it will suddenly decrease in speed and stop, acting like a, hence its name—trap. It is a downgraded version of Diep.io's Trapper.

Tier 3: Level 25

Upon reaching Level 25, the player may choose to upgrade to one of these Tier 3 specializations:

Twin Upgrades

	Double Twin The Double Twin mirrors the Twin’s guns to the rear, adding an extra defense to the back. It boasts increased penetration, but damage is decreased and its Recoil is technically disabled.
	Triple Shot Selecting the Triple Shot class adds another Cannon and spreads the guns across the front. Triple Shot has increased penetration and damage and can cover a wide area with Bullets, but direct firepower is significantly less than before. Recoil can propel the player backward.
	Gunner The Gunner rapidly fires small Bullets in a straight path from four frontal miniguns. Reload speed doubles again at the cost of decreased Penetration and damage per shot. Recoil is reduced significantly. Also upgrades from the Machine Gun.
	Hexa Tank The Hexa Tank removes its two frontal cannons. However, this is not very problematic as it has six cannons equally spaced apart. This turns it into a good farming and multi-killing tool. This could be the Arras counterpart of the Quad Tank. Also upgrades from the Flank Guard.

Sniper Upgrades

	Assassin The Assassin's cannon is now put behind a trapezoidal base. This is to distinguish the differences between an Assassin and a Sniper. Its Field of View (FoV) and bullet speed is also increased compared to that of a Sniper's, but its reload speed is decreased even more than the Sniper's.
	Hunter The Hunter gives a smaller cannon, stacked behind its now-widened Sniper cannon. This allows it to fire two bullets at a time, with one of them being smaller than the others. Field of View (FoV) is slightly increased compared to the Sniper, but it also has a slower reload speed.
	Minigun The Minigun now converts the Sniper cannon into three Basic cannons. It is good for killing low-level tanks due to it being a preciser version of the Machine Gun and the lesser version of the Streamliner. It is essentially a Streamliner but with lesser amounts of cannons. Also upgrades from the Machine Gun.
	Rifle The Rifle narrows its Sniper cannon, which now shoots smaller-than-normal bullets at a faster pace than the Sniper's but also dealing lower damage. Good for beginners as it shoots at a decently fast rate. This is what makes it like a hybrid between the Sniper and the Machine Gun, but weirdly the Machine Gun doesn't upgrade to this class. Used to have no upgrades until an update that added Musket as the Rifle's only upgrade.

Machine Gun Upgrades

	Artillery The Artillery replaces its trapezoidal cannon with a Pounder cannon, plus two small side cannons near its main cannon. The side cannons shoot at about two times the fire rate of the main cannon. The main cannon still shoots somewhat large bullets slowly but packs a punch. Also upgrades from the Pounder.
	Minigun The Minigun now converts the Machine Gun cannon into three Basic cannons. It is good for killing low-level tanks due to it being a more precise version of the Machine Gun and the lesser version of the Streamliner. It is essentially a Streamliner but with lesser amounts of cannons. The Field of View (FoV) is increased to the same as the Sniper. Also upgrades from the Sniper.
	Gunner The Gunner rapidly fires small Bullets in a straight path from four frontal miniguns. Reload speed doubles again at the cost of decreased Penetration and damage per shot. Recoil is reduced significantly. Also upgrades from the Twin.

Flank Guard Upgrades

	Hexa Tank The Hexa Tank gives three more cannons, totaling six cannons that are equally spaced apart. This turns it into a good farming and multi-killing tool. This could be the Arras counterpart of the Quad Tank. Also upgrades from the Twin.
	Tri-Angle The Tri-Angle removes the two back cannons and replaces them with two smaller back cannons that are closer to each other and are meant for propelling. There are currently two distinct Tri-Angle builds: The ramming one, and the bullet one.
	Auto-3 The Auto-3 converts its three Basic cannons into three Auto Turrets that fire at any hostile entities with decreased damage and increased reload and bullet speed. The Auto-3 also automatically spins, but slower than when Auto Spin is activated.
	Trap Guard The Trap Guard eliminates its two back cannons and replaces them with a Launcher that behaves normally. Both the Basic cannon and the launcher have the same statistics. Also upgrades from the Trapper.
	Tri-Trapper The Tri-Trapper converts its three Basic cannons into three Launchers that shoots traps. Recoil still doesn't have any effect when using this tank. Its number of launchers allow for quickly setting up a wall of traps. It could be the Arras counterpart of the Tri-Trapper. Also upgrades from the Trapper.

Director Upgrades

	Overseer The Overseer gives one more Spawner, allowing for increased Drone spawning rate. It can also spawn four more Drones, for a total of nine. Therefore it is easier to overwhelm an unprepared enemy with its Drones.
	Cruiser The Cruiser replaces its Drone Spawner with two inverted Spawners that produces Swarm Drones, small drones with limited lifespan at a fast production rate. The Swarm Drones have drastically increased movement speed but decreased damage and penetration. The Cruiser can technically produce unlimited amounts of Swarm Drones, however as said before the Swarm Drones have limited lifespan.
	Underseer The Underseer gives one more Spawner similarly to the Overseer, but does not work the same way. The Spawners produce two Square Drones that can convert Squares into more Square Drones, potentially allowing for a Drone swarm even greater than an Overseer can do.
	Spawner The Spawner replaces its Drone Spawner with a Minion Spawner that can produce up to four Minions, small Basic-like tanks that encircle targets that they shoot. The combined firepower of all Minions it spawns can turn the Spawner into a tank with good DPS.

Pounder Upgrades

	Destroyer The Destroyer widens its predecessor's barrel, allowing it to fire a larger and even more powerful Bullet that produces even more recoil than before, allowing for ramming builds to be an option on top of bullet builds.
