Cryptozoic Entertainment will release Enders Game: Battle School, a board game based on the sci-fi film of the same name that will be released in theaters November 1st.  Cryptozoic hopes to have the game in stores "by the time the movie is in theaters."  MSRP is set at $25.00.
Ender's Game: Battle School is a two-player game set in the zero-gravity arena of the International Fleet's Battle School.  Players take the role of either Ender Wiggin and the Dragon Team or Bonzo Madrid and the Salamander Team, and then use Commander cards with special abilities (some for the whole team, some that only help the commander) to attempt to capture the other team’s gates or freeze opposing team players with laser-light guns.  The player who completes either of the goals first (capturing all the gates or freezing the opposing commander) wins.
The first trailer for Ender’s Game can be seen here (see "'Ender's Game' Trailer") and there are shots of the Battle Room at roughly  :42 - :46.
