Field of View
Strong Against: Single Enemies, Necromancers, Trapper branch, tanks with low Bullet Penetration and/or RoF (Rate of Fire), slow Smasher branch tanks, tanks that lack concentrated fire such as the Octo Tank or Spread Shot (if with correct build), Auto Classes.
The Streamliner is a true rapid-fire tank, and is built for a fight. Indeed, farming with the Streamliner is a time consuming and unrewarding exercise (it takes almost a full second to destroy a single Pentagon with seven points in reload, Bullet Penetration, and Damage), due to its terrible Bullet Penetration and weak Damage. For Team DM and/or Domination, It is best used against individual enemies as they try to enter the center of the map or leave their base, since it shoots so many Bullets so fast it is almost impossible for individual tanks to escape. Flanking is an especially devastating tactic that almost always succeeds with this tank, as you can trap the flanked enemies between your powerful stream and your allies from your team.
If used with a correct build, the Streamliner is effective against spammers with spread fire such as the Penta Shot, Spread Shot, Triple Twin or Octo Tank. A build with maxed out bullet stats and at least six points in reload can out penetrate the spammer's fire pattern almost every time, however they may easily kill you if you are low on health, if any possibility like this happens, retreat then come back.
For this tank, your offense is your defense. It is therefore wise to invest everything you can in Bullet Damage, Penetration, and Reload. Some speed to retreat and health to take some damage is helpful, but it should not be your first line of defense. Bullet shielding and retreat are the best ways to protect yourself, so it is highly advisable to learn how to do so. It should be noted, however, that a Glass Cannon build makes the Streamliner a far more dangerous foe, giving it a high rate of fire and fast Bullets, making it capable of cutting through areas with effective results. For this tank, Movement Speed is a variable stat in necessity: the health can be upgraded to provide a stronger tank, and Movement Speed is not terribly necessary unless going against a Drone or melee user with high health. In such a case, it would be recommended to avoid them altogether unless necessary, in which case a fleeing fire can cut them down to a decent level. In Team Deathmatch, one can use it for defense of bases when your own base is nailed down, as it can cut through quite a few Bullets with a Glass Cannon build. However, a Streamliner with this build should never enter a fight against multiple opponents with Area Denial unless playing with a team that is supporting them, as the multiple enemies will overwhelm them even with flicking (see below).
A trick, known as “flicking,” involves you moving your mouse in a short direction, up and down or left and right, depending on which direction you are moving in. Flicking allows you to spread out your shots, increasing the chances to hit your enemies or hit a large group of enemies. Use this to your advantage when it is necessary.
The Streamliner true anti-Trapper tank, due to the thin bullets that can seep through the traps and hit the victim. This especially makes it work well against the Auto Trapper, however the Auto Turret can focus on you and easily finish you off if you aren't fast enough, if you are being attacked by the turret, simply dodge as many bullets as possible.
This tank has the ability to camp around in the Pentagon Nest, your high rate of fire is great for farming the Pentagons and wiping out the Crashers that spawn in the nest. You may also help yourself to quickly destroy Alpha Pentagons to gain extra EXP when going for the top of the leaderboard. If any tank however enters the nest, you should leave unless you can handle them well depending on your skill or the terms of the enemy(s)' attack ability.
The Streamliner is a good choice for Survival, as it can kill most players from reaching classes that can counter the Streamliner, like the Overlord or Triplet for instance. Not only that, but if the player takes the path through the Machine Gun, then to the Gunner, it would be easy to get to. It’s probably best to avoid going the path of the Sniper to the Hunter, since both of those classes are hard to farm with, due to their lack of Bullet spread and Reload.
Against the Streamliner
Rangers can prove effective against the Streamliner if caught off guard. Due to its low health, a direct hit could potentially put it down for the count. However, unless it is otherwise distracted, the first shot has to be the one that counts. Otherwise, it can ward against your direction with its stream while it retreats.
Tri-Angle upgrades with maxed Bullet Damage, Penetration, and Reload can chase and block the Streamliner’s Bullets at the same time as their Penetration is one of the weakest as them being a subclass of the Gunner, rendering them helpless.
Overseer type classes are extremely effective against a Streamliner, due to the thin bullets not as strong, most of the drones may easily survive the fire power and hit the Streamliner. However, glass cannon Streamliners with high speed themselves may easily kill you if your drones are slow or can't catch them at a perfect moment, otherwise, spread out the drones and claw the Streamliner in (if in a situation where the Streamliner is using a glass build).
An effective technique is surrounding (or flanking if playing as another Streamliner) the enemy Streamliner, which is not usually difficult considering its low speed, since it is so difficult to directly approach unless distracted. In Team DM, pairing up with another high DPS tank and setting up a crossfire will force the Streamliner to retreat or die, due to the fact that it can only defend from one direction at a time. In FFA this effect can be duplicated by spamming Bullets in the direction of a Streamliner which is already defending against another enemy. Another strategy is to use Destroyer or Annihilator, to counter the Bullets, as they can plow right through if the correct stats are upgraded, however, if the Destroyer has a slow rate of fire it is very easy for the Streamliner to overpower it.
If done correctly, due to the Streamliner not having as much damage per Bullet, a Booster using a Body Damage ramming strategy can ram into it with almost no problem. The Booster can outrun and out spin the Streamliner, and you can take it when it is not looking at you.
Since the Streamliner’s Bullets are very thin, any tanks with basic Movement Speed upgrade can outdodge the Bullets; even the non-rammer classes tank can come near it. However, Gunner-sized Bullets aren’t effective against the Streamliner because of the Bullet Penetration. (The Penetration is not so great with the Streamliner compared to other Tier 4 tanks but can defeat the Gunner without any problem).
In the first moments of the Streamliner's release, it used to only branch off the Hunter, later on the same day, it was made to also branch off Gunner.
This has the fastest directional RoF of any of Sniper’s upgrades and possibly all tanks in the game.
This is the first Sniper upgrade with a relatively fast reload.
This tank has the highest single-point DPS, therefore making it a great tank against smaller objects or enemies.
It’s straight rapid fire is reminiscent of a Gatling Gun.
The Streamliner has the weakest bullet damage and penetration out of all Sniper classes.
Despite the high rate of fire, the Streamliner does not have a very large amount of recoil, which could possibly be a balancing act so that the Streamliner can’t escape other fast tanks.
Like the Twin, the Streamliner also has an alternative firing pattern. The default is when all Bullets fire in a straight line, but the secondary pattern, where they shoot out as clumps of five Bullets at a time (it takes time and repetitive usage of the Auto Fire button, however) is also available.
As with the Spread Shot, this tank was actually a fan idea added to the game. They were from the same place, too.
The fan version of this tank had six barrels, but the version in game only has five.
