[1][2] The game is set in the United States in the mid-21st century, after a nuclear war started by a cybernetic revolt, which molded the continent into a barren wasteland.

It is a semi-intelligent carnivorous vegetation that grows very quickly, advancing north from Latin America.

Players take turns placing their tiles, representing units and modules (augments) on the board.

[1][2] A second edition (in English) was released at SPIEL (the Essen game fair) in 2007, and a promotional 5th army (Doomsday Machine) was given to buyers at the Portal Publishing booth.

At Pionek (a game convention in Gliwice, Poland) in 2007, a small supplement (Mad Bomber) was given out.

[1] It was published in English by Z-Man Games, with an expanded board and improved components; this edition includes the Mad Bomber and Mercenary tiles.

Additional materials in multiple languages (inc. English-language translations of the expansions) are available at the relevant games articles at BoardGameGeek.

Tishkovskiy noted that there were two stand-alone expansions for the game and was grateful that "it is not at all necessary to have the basic version to play.

Buy a small, inexpensive add-on, and then decide whether it’s worth shelling out for the original box or not.

Overall he praised the third edition for higher components quality and improved rules compared to the older versions.
