The BattleGrounds 2 1.1b is a new version of the Revolutionary War Mod for Half-Life 2 released on the bgmod.com forums September 28 2007. Among many changes, bug fixes and new features, the voice command menus have been extended to contain tactical voice commands such as "Flank left!", "They are behind us!" to make up a total of 18 voice commands and one battlecry, now bound on a seperate key, C. Every class has a different, distinct set of voice commands with 2-5 variations on every choice. All now 13 maps have been revised and polished for this new release. The melee hit detection has been increased greatly to the satisfaction of both devs and players.
Got interested? Battle it out now as either officer, soldier or rifleman on the British or American side and seize control of the thirteen colonies!

Important note for server administrators
Remove 1.0b before installing 1.1b.
We've fixed the players launching into air bug by removing the .phy model for the bullet. This means that you can't simply install 1.1b over 1.0b. You should delete 1.0b first (keep any extra maps and whatnot) before installing 1.1b. It's also a good idea for the simple reason that a lot of the directory structure has changed which means less disk space used compared to overinstall (duplicate files etc). Of course, you can simply delete the phy model aswell (models/game/bullet.phy IIRC).
