Atomic Combat is a 'location guessing' game in the spirit of Battleship. You have factories, cities, research centers, reactors, silos, airfields, and hopefully enough nuclear weapons to destroy your three closest neighbors. However, you don't know where their resources and cities are.
You are firing blind into a grid of possible locations, trying desperately to maim, kill, or irradiate as many citizens of your alleged enemies as possible. The problem is that they're all doing the same thing.
