Finish the mission targets to unlock new characters. This can be done in musou mode or free mode.
Xbox 360 Dynasty Warriors 6 Hint: Extra Height
Some officers can get a little bit more height from their jumps. Use a Strong attack while in the air to get a little more height. With practice, you can get most officers past some high fences the horse can’t clear.
Since you can always summon a horse from anywhere (it teleports), you can use this to get across certain maps.
Dynasty Warriors 6 Hint: Achievements
All the achievements are secret, but they are all relatively simple. Get the majority of the achievements by unlocking new officers (just complete mission targets on Easy or Normal) and by completing the Musou mode with each officer (on any difficulty).
Additionally, there are achievements for completing all the mission targets and clearing all the stages.
Clear Musou mode with all the available officers (solo or co-op doesn’t matter, but all the officers available in Musou mode need to clear it). Additionally, all officers need to attain level 50 (which effectively maxes out their skill trees).
Lastly, take first place in the records for all challenges (in Challenge Mode): Rampage, Sudden Death, Speed Run, Havoc, and Gauntlet.
