I never had the historical missions expansion originally, but I remember there being some "bounty hunting" missions in the original game. It was basically a "boss rush" mode. The levels were smaller and there was a level for pretty much every boss in the game, are these in this release?
never mind, I found it. It's under "marshall training" under historical missions since this has the expansion "handful of missions" with it too. In the original release, this was just an extra menu option.
