Streamliner

The Streamliner is a tier 4 upgrade from the Hunter and Gunner and can be selected at level 45. It may not further upgrade.

Technical

Design
The Streamliner features a circular base and 5 barrels, each barrel being overlapped by the previous one. Unlike the Predator, the barrels have the same width.

Strategy
Strong Against: Single Enemies, Necromancers, tanks with low penetration and/or ROF

Weak Against: Bullet spammers, multitudes of enemies, tanks with high Bullet Penetration, other Streamliners.

As the Streamliner
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 7 points in reload, Bullet Penetration, and Damage), due to its terrible Bullet Penetration and weak Damage. It is best used against individual enemies as they try to enter the center of the map or leave their base, since it spams so many bullets so fast it is almost impossible for individuals to escape. Flanking especially is a devastating tactic that almost always succeeds with this tank, as you can trap the flanked enemies between your powerful stream and your allies.

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 is the best way to protect yourself, so it is highly advisable to learn how to do so.

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.

Surrounding (or flanking if playing as another Streamliner) the enemy Streamliner, which is not usually difficult considering its speed, is an effective way to put it down for good. Since it is so difficult to directly approach unless distracted. Pairing up with another bullet spammer 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.
