Once upon a time, there was an empty arena. Suddenly, blue circles started spawning everywhere. They fought each other, crashing into anyone they see around. Most of them died, but some were very experts at ramming and survived. They formed the "MG" clan. In the meantime, pentagons lived peacefully in the center of the arena. No one dared to go there because of the pink triangles who defended their base.
Slowly, tanks were getting better at fighting. They got a barrel to shoot instead of ramming. They became dominant and took over the pentagon area. After a couple of days, all normal circles got a barrel.
The tanks fought and fought, but they found that they're all the same. Everyone wanted to get more barrels on their circles. And that's how classes appeared. The tanks now have a choice to transform into 4 better tanks: Twin, Sniper, machine gun and flank guard. Each one of those tanks had strengths and weaknesses, for example, the twin had better chances to hit the opponent thanks to two barrels on one side. The flank guard though also had two barrels but instead of being near each other they were opposed, one from the front and one from the back. Sniper preffered to stay with only one barrel, but instead, had a very big field of view and strong, focused and fast bullets. However, machine gun was lazy, and had one big barrel that shoots random bullets.
The "MG" clan didn't like the idea of "shooting", so they presented the tri-angle, the first tank based on ramming with speed boost. Bit by bit, the tri-angle developed into what we call now "booster".
Other tanks also developed better and more efficient models, like flank guard which upgraded to quad tank, which shoots 4 bullets at once from all sides. While all that was happening, some tanks wanted to team with their friends, so Team Death Match (a.k.a TDM) was added. This new mode had two teams, red and blue. You simply join one of the teams and help dominating the server. Many tanks died, but they learned from their mistakes. In the meantime, some tanks discovered a new danger. It was big, yellow tanks similar to destroyer but with the size tripled. Some tanks around tried taking it down, but it was too strong. It killed them all. All tanks decided to team against those beasts, but they wanted some sort of competiton so they split into two teams. Again, red and blue. New beasts (which are known as dominators) spawned everyday and tanks until today are still fighting them each time they spawn. It became a daily activity to some tanks and they found that very fun.
Away from dominators, a tank from the sniper tree wanted some special powers. It developed a special power of turning invisible. It was a very special tank out there, but most of tanks turned their vision to another special tank: the overseer. It had small triangles around it and it used its mind to control them. Those two tanks were very special, until other tanks got their own special powers, like the trapper who shoots deadly traps, and auto-3 which detects near shapes/tanks and automatically shoots them.
By the time that was happening, each team wanted to get a leader. So motherships were introduced. They are huge tanks that have drone spawners all around it. Having all stats maxed except health regeneration, it needed a full team in order to take it out. Each time a mothership dies, a new tank gets its control. Getting the control of a mothership is not easy; you have to be very lucky.
A new tank was introduced: The hybrid. The destroyer decided it was outclassed by the dominator, so it deveoped a new model. It now has a drone spawner on its back. Sadly, it cannot control them. One tank cannot hold both bullet and mind control powers, it's too much.
The pentagons felt that the tanks are very dominant, and wanted to get rid of them to let the pentagons live. They called their master, the guradian, to solve this issue. Even more bosses and masters came with the guradian, to control the tanks.
As more tanks were born, the team-based minigames now had four teams to hold all tanks. It became even more fun to everyone.
Even more minigames were added, like tag mode and sandbox. Killing shapes and attacking other players became the best activity for these tanks. Although they attack each other, they are still friends and help each other whenever possible. However, they are still fighting to remove "MG" teaming. They never learn that teaming in mass is not fair on FFA.
