The Machine Gun

PDF download Download Article
  1. The Machine Gun is a tank with a wider cannon, and it reloads faster, but its bullets are inaccurate.
  2. Once you reach level 30, you can upgrade to either a Destroyer (large bullets but slow reload. With max bullet damage and penetration, can kill tanks in one shot.) or a Gunner (four mini-guns).
    • At level 45, the Machine Gun can upgrade directly to Sprayer, which sprays small and large bullets.
  3. Once it reaches level 45, the Destroyer can upgrade to a Annihilator, Hybrid, Rocketeer, or Skimmer.
    • Annihilator is a Upgraded destroyer, with a bigger cannon and bullet.
    • Hybrid is a Destroyer with drone spawner that gives you 2 drones.
    • Rocketeer shoots bullets like rockets, shooting bullets behind them as they travel.
    • Skimmer is a tank that shoots spinning projectiles that also fire bullets as they spin, somewhat similar to the Rocketeer.
    • Once you upgrade to Rocketeer or Skimmer, you can no longer kill max health tanks in one shot.

    • Auto Gunner is Gunner with one auto cannon mounted in the middle of the tank.
    • Gunner Trapper has two small guns in the front and a trap layer in the rear. This creates a trail of triangular traps to damage enemies.

Method 5 of 6:

The Sniper

PDF download Download Article
  1. The sniper is a tank that has faster bullet but slower reload, and you can see further. You also move slower. The damage of the bullet also increases as it travels further.
  2. At level 30, Sniper can upgrade to either a Hunter (shoots two bullets at once), an Assassin (very fast bullets and stronger bullet damage, and even bigger field of view.), a Trapper (shoots triangles that damage shapes and enemy tanks), or an Overseer (creates triangular drones you can control).
  3. At level 45, Overseer can upgrade to 6 tanks: The Overlord, Necromancer, Manager, Overtrapper, Battleship or Factory. [2]
    • Manager is like Overseer, but it can become invisible and has one less spawner.
    • Necromancer makes you square-shaped and transforms normal squares you (or your drones) collide with into square drones you can control.
    • Factory makes your tank square as well, and will produce up to 6 drones that are like mini tanks (there is even a chance a new player will spawn on you).
    • Battleship has four trapezoid spawners attached to it like Twin Flank but with the spawners being smaller. It uses Drones of its team’s color. [3]
    • The Overtrapper has two drone spawners and a trap launcher that are of equal distance from each other.
    • Overlord is like Overseer, but it has two extra spawners across from each other and perpendicular to the two already on the tank. This increases drone stats.
    • Holding right-click will make your drones spread out beyond sight.
  4. Assassin can upgrade to a Stalker (becomes invisible if not moving) or a Ranger.
    • Ranger only upgrades how far you can see. It has second longest sight range.
  5. The Hunter upgrades at level 45 to either Streamliner (5 cannons in 1) or Predator.
    • Predator shoots three different-sized bullets. Holding right-click on the mouse enables a very far-seeing ability. This ability makes predator the farthest-seeing tank in the game.
  6. At level 45, Trapper has 5 upgrade options: The Tri-Trapper, Mega Trapper, Overtrapper, Auto Trapper and Gunner Trapper.
    • The Tri-Trapper has three trap launchers equally apart from each other.
    • The Mega Trapper decreases the reload but increases the size and strength of the traps significantly. It also has a larger launcher. [4]
    • Auto Trapper is trapper, but with an uncontrollable auto turret on top.
    • Gunner Trapper has two small gunner cannons in the front and a trap layer in the rear.
    • The Overtrapper has two drone spawners and a trap launcher that are of equal distance from each other.

  • Question
    Is the Factory the best tank?
    Jack Herrera
    Community Answer
    The Factory is a great tank! It's hard to know which tank is the "best", but the Factory can defend itself by letting a bullet (not a Destroyer or Annihilator bullet!) touch you, and then your minions (drones) will attack what has hit you while you stay safe.

  • Question
    Why can't I get the Smasher Tank?
    Jack Herrera
    Community Answer
    You must get to Level 30 as a basic tank, which means no choosing Twin, Sniper, Machine Gun, or Flank Guard until you are at Level 30, then pick the Smasher option.
