Maps

There is an expected 22 maps in Tanker as of the unreleased version 2.7.

Biomes
The maps will be split into multiple Biomes including Desert, Rainforest, Metro Siege, and '''Artic. When Tanker is released in version 5, it's likely that the proposed Spacefight''', which will involve planets like the lore-induced Vindtaan II and the fallen moon Jeromino, will be in the available list.

There are planned biomes which have never made it into the game, such as Pilot's Sunset (a play on words of the musician and animator PilotRedSun) and Fart Knife.

Trivia

 * There was a former gamemode called "Minatogahakaisareamerikagaokotteshimausensō", which literally means "A war where the harbor is destroyed and the United States gets angry". This was later shortened to "The Harbor". It was later removed in order not to make fun of Pearl Harbor victims.
 * There was a planned "tank soccer" gamemode, but then again it's already existing in the form of Rocket League.
