The ride is enough of a crazy Creed to be a surprising success. [July 2013, p.77]
The Tyranny of King Washington ends with an episode that includes all the characteristics included in the previous chapters. 'The Bear Power' is featured as the last mystical ability of the Ratonhnhaké:ton, dramatically changing the play style we could see in previous Assassin's Creed games.

This three hour long conclusion to the King Washington-DLC does not manage to enthrall us as we would like it to do. But we do have to admit we had a great time transforming into a mighty bear, destroying all who were foolish enough to stand in our way. [June 2013, p.91]
It would be a much easier recommendation at half the price.
If you have played the first two episodes of this DLC and want to know how the story ends, this is not a total waste. Get it over with 'Tyranny', remember for its nice core idea and its two actually quite good first episodes and not for the weak ending 'The Redemption' so listlessly provides.
