Streamliner

**Streamliner** is a Tier 4 weapon upgrade utilising 7 barrels stacked in the same direction. The Streamliner is notable for having one of the most recognisable subclasses, being Streamliner-Saw. This is because people use the recoil of the Streamliner's cannons for speed as an advantage when travelling around the map and conflict with other players.

## Technical

Streamliner consists of 7 barrels stacked in a line. This allows for focused firing. It evolves from Assassin, Trio, and Gunner and evolves to Rationalizer.

## Strategy

Your main strategy will depend on whether you are playing Streamliner traditionally or as its subclass **Streamliner**-Saw.

### Streamliner

#### As a Streamliner

**Streamliner** thrives on flanks and is able to fire outside the range of opponents, often catching them by surprise. The large storm of bullets can overwhelm your opponent, and the high mobility of the tank allows for easy hit-and-run manoeuvres and potential kills on lower-level tanks.

* Streamliner lives and dies on flanks, as its DPS is very poor (0.6/s), so it is highly recommended you exit as soon as possible upon entering a fight. Feel free to re-enter the fight soon after as you will continue to appear unexpectedly. This is the best way to get kills as a Streamliner, as its incredibly precise shooting makes it easy to aim with when you're in a pinch.
* Slow classes like Octo and most bullet-based Celestials are incredibly vulnerable to Streamliner's burst damage and speed. Heavy classes like Bullet Annihilators and Alphas are also easy to kill provided you're good at aiming.
* However, when used in a traditional offence, it is nullified by almost everything with even slight amounts of defence such as offensive cannons from Quadro and Minigun, drones from Executive, Emperor, or front-facing traps from Riot and Amalgam.
* Marksman is easily the biggest scare as a Streamliner as it's the only tank with a higher FoV than Streamliner, which makes it impossible to flank or block.
* Reload is a relatively redundant stat with Streamliner, so instead invest most of your points in Speed for better flanks or Damage for better burst damage.
* Most standard trappers like Palisade and Shrapnel will fall prey to Streamliner's powerful and constant focus firing, making it a decent support pick-based tank.

#### Against the Streamliner

* Do not get tunnel-visioned. Stay vigilant, as Streamliner's high mobility can allow it to get a decent bit of damage on you every time it goes in for an attack. If you're prepared, then you can easily block Streamliner's weak bullet stream.
* Streamliner has a relatively low DPS compared to most DPS tanks. Engaging in direct fights with it will usually involve you winning. If it is cornered or gets greedy, the Streamliner will be a decently easy kill.
* Marksman counters this tank very hard. The inability to flank renders Streamliner worthless. If you're really struggling against Streamliner, play as a Marksman.
* If a Streamliner is approaching a Trapper or any of its subsequent upgrades, focus all fire on the Streamliner to minimise the threat it could pose to your team's defense.

#### Matchups

* **Strong Against:** Slow classes like Octo, Weak and Slow Celestials, Heavy Classes like Annihilator, Hybrid, and Alpha, Trappers, all tanks except Rammers when surprised.
* **Weak Against:** Anything with higher penetration, Marksman.

### Streamliner-Saw

Offensive Streamliner isn't the only way to play as a Streamliner. Streamliner-Saw is a common subclass of Streamliner based around the body part Saw, turning the tank into a flank-based hit-and-run class into a rammer. As a rammer, there are also some strategies. However, a rammer will be much easier to use because the acceleration is significantly higher than any other diep.io-like games, meaning you can turn around and aim at the target quickly.

#### As the Streamliner-Saw

* As a **Streamliner-Saw,** aim for every slow tank - you can have a good meal as the movement speed gap could possibly be very high, as the maximum movement speed is 15 points. If they don’t even have a single point, you can get easy XP. However, be warned about high-level Ziggurats, especially Marksman because Ziggurats (If you want to do speed rams, it is not suggested to use Ziggurat as it reduces your speed.) have unexpectedly high HP and you might die because of the high-level gap (level increases health) and their body’s health. But for Marksman-Saw, you can ram them with clever movements.
* **Bullet Spammers** are also quite convenient to kill. You don’t even need to avoid their bullets if they’re much slower than you because they do slight damage. However, if they are as fast as or faster than you, don’t ram straight or you will lose all your health anytime. Try to ambush them - especially when they are farming shapes.
* **Trappers** are way harder, like Amalgam or Riot, and even more challenging if they are equipped with Inferno. Traps are sturdier than drones and bullets, and ramming seems impossible if they are careful. Infernos deal high damage to players and have high radius, so it will be hard. It is recommended to go with something like Marksman.

#### Against a Streamliner-Saw

* If you are a trap spammer, you won’t need to fear because you have enough power to offset their threats. You have strong traps to kill them when trying to ram you, and you can also pair it with Inferno so that you can kill the **Streamliner** he rams you.
* A **Drone Producer** like Emperor is ineffective against it. Due to your low drone health & damage, you can't kill it even with all your drones. Just try your best to avoid his body and keep summoning your drones to ram the Streamliner.

#### Matchups

* **Strong against**: Bullet Spammers, Tier 1 Celestials (Without auras), Destroyer branch, Mass Drone Producer.
* **Goes well with**: Almost everything except for the strengths mentioned.
* **Weak against**: Nothing except for tanks faster than you.
