Question: In between Vanished Planet and Hex which one is a cooperative board game that debuted at the World Boardgaming Championships in 2003?

full_context: Document 1: Stratego: Stratego is a strategy board game for two players on a board of 10×10 squares. Each player controls 40 pieces representing individual officer ranks in an army. The pieces have Napoleonic insignia. The objective of the game is to find and capture the opponent's "Flag", or to capture so many enemy pieces that the opponent cannot make any further moves. "Stratego" has simple enough rules for young children to play, but a depth of strategy that is also appealing to adults. The game is a slightly modified copy of an early 20th century French game named "L'Attaque". It has been in production in Europe since World War II and the United States since 1961. There are now 2- and 4-handed versions, versions with 10, 30 or 40 pieces per player, and boards with smaller sizes (number of spaces). There are also variant pieces and different rulesets.
Document 2: Cooperative board game: In a cooperative board game, players work together in order to achieve a goal, either winning or losing as a group. As the name suggests, cooperative games stress cooperation over competition.
Document 3: Flash Point: Fire Rescue: Flash Point: Fire Rescue is a 2011 thematic cooperative board game designed by Kevin Lanzing with the help of firefighters. The objective is for players to work together to rescue people and animals from a burning building before it collapses. Since the initial release of the game several expansions have been published, which add additional scenarios for players experience. These include fires in a high rise building, a two-story house, and a submarine.
Document 4: Shannon switching game: The Shannon switching game is an abstract strategy game for two players, invented by American mathematician and electrical engineer Claude Shannon, the "father of information theory" some time before 1951. Two players take turns coloring the edges of an arbitrary graph. One player has the goal of connecting two distinguished vertices by a path of edges of their color. The other player aims to prevent this by using their color instead (or, equivalently, by erasing edges). The game is commonly played on a rectangular grid; this special case of the game was independently invented by American mathematician David Gale in the late 1950s and is known as Gale or Bridg-It.
Document 5: 25 Words or Less: 25 Words or Less is a party board game where two teams of players take turns bidding words back and forth, until one team allows the other to try to give that number of clues to their team to try getting five words from a card in only one minute. It was first published by Winning Moves Games USA in 1996 and was republished in 2006 as "25 Words or Less: People, Place and Things Edition". The game is no longer in production.
Document 6: Pente: Pente is a strategy board game for two or more players, created in 1977 by Gary Gabrel, a dishwasher at Hideaway Pizza, in Stillwater, Oklahoma. Customers played Pente at Hideaway Pizza on checkerboard tablecloths while waiting for their orders to arrive. Thirty years later, patrons are still playing Pente at Hideaway Pizza, although now with roll-up Pente boards. Pente is based on the Japanese game ninuki-renju, a variant of renju or gomoku that is played on a Go board of 19x19 intersections with white and black stones. Like "ninuki-renju," Pente allow captures, but Pente added a new opening rule. In the nineteenth century, "gomoku" was introduced to Britain where it was known as "Go Bang." (borrowed from Japanese "goban" 碁盤 meaning "go board")
Document 7: Vanished Planet: Vanished Planet is a cooperative board game that debuted at the World Boardgaming Championships in 2003. "Vanished Planet" pits the players against a time limit; the players must succeed in a certain number of goals before this time limit is reached, or they all lose.
Document 8: Pandemic (board game): Pandemic is a cooperative board game designed by Matt Leacock and published by Z-Man Games in 2007. "Pandemic" is based on the premise that four diseases have broken out in the world, each threatening to wipe out a region. The game accommodates 2 to 4 players, each playing one of five possible specialists: dispatcher, medic, scientist, researcher, or operations expert. The game is unlike most board games in that the gameplay is cooperative, rather than competitive. Through the combined effort of all the players, the goal is to discover all four cures before any of several game-losing conditions are reached.
Document 9: Hex (board game): Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus. Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain. One player must win; there are no draws. The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem. It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash. The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production. Hex can also be played with paper and pencil on hexagonally ruled graph paper.
Document 10: ZÈRTZ: ZÈRTZ is the third game in the "GIPF" Project of six abstract strategy games. The game features a shrinking board and an object that promotes sacrifice combinations. Since neither player owns on-board pieces, maintaining the initiative is of fundamental importance.
Document 11: Nine Men's Morris: Nine Men's Morris is a strategy board game for two players dating at least to the Roman Empire. The game is also known as Nine Man Morris, Mill, Mills, The Mill Game, Merels, Merrills, Merelles, Marelles, Morelles and Ninepenny Marl in English. The game has also been called Cowboy Checkers and is sometimes printed on the back of checkerboards. Nine Men's Morris is a solved game in which either player can force the game into a draw.
Document 12: Connect Four: Connect Four (also known as Captain's Mistress, Four Up, Plot Four, Find Four, Fourplay , Four in a Row, Four in a Line and Gravitrips (in Soviet Union)) is a two-player connection game in which the players first choose a color and then take turns dropping colored discs from the top into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the next available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own discs. Connect Four is a solved game. The first player can always win by playing the right moves.
Document 13: Wythoff's game: Wythoff's game is a two-player mathematical game of strategy, played with two piles of counters. Players take turns removing counters from one or both piles; when removing stones from both piles, the numbers of counters removed from each pile must be equal. The game ends when one person removes the last counter or counters, thus winning.
Document 14: TAMSK: TAMSK is the second board game in the "GIPF" Project of six abstract strategy games, and was published in 1998. Players move sand hourglass timers and drop plastic rings around spaces on a hexagonal board in an attempt to limit their opponent's moves. Each player starts the game with 32 rings, and the player with the fewest remaining rings at the end of the game is the winner. The game is unique among the "GIPF" Project games in having time as a central game component, and the manner in which time is used is possibly unique among board games in general.
Document 15: Havannah: Havannah is a two-player abstract strategy board game invented by Christian Freeling. It belongs to the family of games commonly called connection games; its relatives include Hex and TwixT. Havannah has "a sophisticated and varied strategy" and is best played on a base-10 hexagonal board, ten hex cells to a side.
