The game sets up swiftly. Mexican units have a color stripe which corresponds to a 4 or 5 box map edge area of the same color. Rebel units are set up at designated locations on the map. The map works much better IMHO than the SPI design with these squares as it's easy to show the Alamo fort yet abstracted enough to resolve LOS and other conundrums. Unlimited turns until one side wins.
Counters contain a silhouette and drm for melee and fire.
Mex are killed before all the Tex. Basically, the Mex units rush for the walls with the Tex firing like mad. Mex units are two step and are reduced first then killed. And you can't fire at a just-reduced unit in the same turn. So the Mex units are reduced as they near the walls.
