Red Hatchets & Black Powder is a supplement to Fistful of Lead: Horse and Musket allows you to play a small scale wargame in the woods and wilds of North America during the French and Indian War.
You can take on the role of a Captain or War Leader, either leading a troop of brave soldiers, stalwart Rangers, terrified militia or stealthy Natives. Red Hatchets & Black Powder is supplement to Fistful of Lead: Horse & Musket, and is not a stand alone game. You will need a copy of Fistful of Lead: Horse & Musket to play.
There are 10 new scenarios for the French and Indian War. They can be played in order as a campaign if you like, or as one offs.
There is a section on building your Detachment based on more historical lines with ideas for Grenadiers, Regulars, Highlanders, Provincials, etc.
Note: This book was written before the 2nd edition of Horse & Musket so a few names for traits might be different (for instance Stone Killers instead of Ferocious) but the description is there so it shouldn't be too confusing.
