Thunder

The Thunder is a Tier 4 Tank that upgrades from the Mini Lightning at level 45. It has the ability to turn invisible.

Design
The Thunder is a Mini Lightning with a triangle on its body to signify its invisibility ability. It has two drone spawners.

Technical
The Thunder wields 6 fast yet weak drones that it spawns from its spawners. It has a higher FOV than the Director.

The Thunder can turn invisible after staying still for about 3 seconds. Invisible tanks are very, very faint, but someone who studied 16 hours for their eye test to get an A (?) can tell the difference.

While invisible, the Thunder experiences no recoil. This means that you can remain invisible while spawning new drones, although they'll likely still give away your location.

Upgrades
The Thunder is a Tier 4 Tank that upgrades from the Mini Lightning at level 45.

The Thunder upgrades into the following:


 * Cavity (Lv. 60)

As the Thunder

 * Keep in mind that your drones deal less damage than Director. Upgrade Bullet Damage.
 * Be sure to upgrade Bullet Speed while you're at it since it's one of the perks of Mini Lightning branch.
 * You can use this to creeper-aw-man surprise people combined with your high FOV.
 * Turn invisible so, if the enemy doesn't die, they can't pursue you.
 * Turn invisible in areas where tanks like to go, such as near the Pentagon Nest, and prey on them with your high FOV.
 * Don't get too close, since if a crasher touches you, it shuts-down-crashes-*DING*-resets the turning-invisible process.
 * Hiding behind rocks is a great idea, so that stray bullets can't reveal you.
 * Be careful around "crowd-control" or widespread-bullet tanks like Octo-Tank or Spreadling because it's likely that one of their stray bullets will reveal you.
 * If this happens, it's best to have invested in Movement Speed so you can escape.
 * Bullet spammers can easily penetrate your weak drones, so avoid them.
 * Low-ROF tanks like Basic are easy to kill. Plus, they can't attack back.
 * Smasher, ram Propeller and Lancer are very dangerous, because it's likely that your drones won't deal enough damage to kill them. It's very important that you remain invisible.
 * If you see a Minesweeper, you're dead. This statement really *struck* you, right?

Against the Thunder

 * Let's get it out of the way: Thunder stands no chance against the Minesweeper. Sweeps it right off the arena.
 * If you see any suspicious drones with no drone user nearby, shoot at them, since they have to respawn from where Thunder is. Then, you can attack.
 * Smasher, ram Propeller and Lancer are very good, since Thunder's drones are weaker than a stereotypical high-school nerd in PE class. Ok they're not THAT weak but still—
 * Try to avoid low-ROF tanks like the Sniper, and go for tanks with lots of bullets.
 * This includes Octo-Tank, Spreadling, and focused bullet spammers like Triplet or even Twinigun.
 * If you shoot lots of bullets, it's likely that you'll reveal the location of Thunder.
 * Thunder might be hiding behind rocks. If this is the case, use a fast tank like Booster to bomb-rush the rock bunker.
 * A Thunder in Maze mode is quite dangerous, as with all drone tanks in general. Definitely go for Minesweeper.

Trivia

 * Thunder is the noise heard when lightning occurs. The tank was likely named this because it is the auditory component of a lightning strike, i.e. te part you cannot see in reference to its invisibility.
 * Despite Mini Lightning branching from Sniper, this tank does not branch from Huntress.
