Description:
hex-based tactical game
Crimson Fields is a hex-based tactical war game in the tradition of Battle Isle (tm). Two players command their units on a map of hexagons, trying to accomplish mission objectives ranging from defending important locations to simply destroying all enemy forces. The game can either be played in 'hot seat' mode, via email, or against the computer. Tools are available to create custom maps and campaigns. You can also play the original Battle Isle maps if you have a copy of the game.
