There have been a number of tweaks since the first play sheet for the game was uploaded. The current play sheet is more comprehensive and essentially captures many/most elements of the game play that can be used with the current Muskets & Tomahawks rules.
Therefore, here is an updated current play sheet. Any other changes I shall make will be specific to this post and put in the comments section so check those to see that you have the current version.
