Here is an idea for the developers which will help them enhance the gameplay by making the fighting more realistic.
One thing that I have noticed during game play is that the assassin could be enhanced with more skill during defensive movements.
I mention this as many of the movements that the assassin performs are very "static" in nature and some of the defenses that employ grappling movements are also fairly static in the sense that when an attacker throws an attack, they do not cover much distance, which means that the defending assassin does not have much of the attackers energy to redirect and use against his opponent.
A very important concept for battlefield martial arts.
It would be nice to see the assassins using more skill when performing a defense technique, such as drawing an opponents attack onto him, in order to then redirect and throw his opponent.
Of course, for the defensive assassin to do this, he would have to have an attacker throw or swing a fully committed attack at him.
This type of attack is far more common among wild untrained and perhaps cocky wild men.
An example of this type of defense would be in the execution of tomoe nage circle throw, where the defender redirects his opponents attack and redirects its energy with grace and skill in order to throw his attacker for six.
This throw is often used in Judo, however, please be aware that most throws are executed in a Judo match after the 2 opponents have grabbed each other and are both fighting to break each others balance prior to executing a technique.
This type of simulated fighting is of course not completely real, in the fact that most people will not attack you by grabbing your clothes and then try and throw you.
Also, in a full on assault, both fighters are not likely to abstain from using atemi waza (strikes).
So. performing such a throw against perhaps an attacker who is throwing a fully committed attack such as a front straight, swinging or roundhouse punch or thrust with a bladed weapon would be really effective if executed successfully.
One other observation is that you could also incorporate several refined techniques from several martial arts styles that incorporate lethal force with the intention to maim or kill.
Such techniques are found in such arts as:
Where as these arts are not successful in perhaps modern competition styles such as those found in UFC.
They are designed to be effective in a different arena, that of the street, where there are no rules.
Shots to the eyes, throat, kidneys, knees and groin, not to mention the spine are the first option.
Where as the usual punches and kicks to other area's are used in order to set up a more lethal technique.
Although many may not realize, many of the throws used in Judo / aikijujutsu and even aikido are also considered lethal techniques,
as although these techniques may not be lethal when training on big absorbent mats, when used in the street, the hard surfaces of the normal street environment is less forgiving.
Anyway, just a idea.
I would also consider putting in another game, an opposing clan of assassins. who use the same methods that you do, who need to be intercepted, distracted, fooled and stopped in order to protect society.
Perhaps you would consider writing an alternate ending where the bad game developers who have twisted their audiences perception by going back in time to manipulate events all get murdered by the righteous assassins who need to clear their names of this slander.
Well theres one for the smart asses in the game industry to think about.
