Neuroshima Hex

Neuroshima Hex! is a strategy game set in the post-apocalyptic world of Neuroshima, a Polish role-playing game. Each player leads one of four armies: Borgo, Hegemonia (Hegemony), Moloch, and Posterunek (Outpost). Each army deck consists of 34 tiles: soldiers, support tiles, and special actions. You win when all enemy headquarters are destroyed or when your headquarters is the least damaged at the end of the game.

In 2007 and 2013, the game had graphical facelifts, somewhat modifying the iconography. Note: each army (whether base game or expansion) is compatible with every version (1.0, 2.x, 3.0). Only the art styles and icon graphics differ mildly.
The game had different editions with different components/bonuses alongside the 4 base armies (big board, bonus army, puzzles, etc.). See different editions for details.
Tile width and thickness strongly varied depending on edition, and even on a same editor slightly varied over the years. This does not affect play, but may affect some storage solutions.

Due to multiple versions and expansions, see the Neuroshima Hex! english FAQ
The game is also expanded by Unofficial Neuroshima Hex! expansions, available here on BGG.

Note: There is no solitaire bot/AI/system to compete against. The only options for "solo" play are soloing multiple factions yourself, or solving puzzles (like Chess checkmate problems) available in some editions and expansions.
