Bug in the Guild challenges of Assassins creed brotherhood

[Ikhyd]

I really love to play Assassins creed brotherhood on the Xbox of mine. well I am trying to get the guild challenges which are associated with Mercenary and Courtesan guilds. I have found that both the challenges are does not seems to be update till now. I have also seen that Courtesan distraction challenge does not seems to be update. I have dedicated this particular thread to get all the gamers who have been seen or facing this particular problem while doing this challenges in the game.

Well I am suspecting that you are killing all the guard post which are located at the guard post. If that is the thing then let me know whether they are arms crossed or something like that or what? Also I wanted to know whether they are standing exactly in the front of the doors or they are standing at the any other part of the game. let me know the thing which I have asked all above in this post as soon as possible.

I let you know that I have done the crossbow in the memory so that you will be able to get colosseum to play. You need to think that it is an exit stage. I have seen that there are lots of load at the entrance of the colosseum. Well that particular load is used to protect colosseum from the attacks. So I think you need to replaying the memory so that you can rescue caterina again and again. At the part of the mission you will be able to the purchase the time of her in order to get the hideout. Once you have done you will be able to complete the challenges.

I have seen that sometimes it gets updated and sometime it did not seems to work at all. I think I have completed the thing but the reward to completing the entire guild challenge would be the Mercenaries which I need to found in the hideout of the Isola Tiberina. Still I have not found the Bartolomeo's Axe. However I have managed to get the Sword of Altaïr, Maria's Dagger and La Volpe's Bite by completing with the respected challenges in the game.

Finally I have got the idea to kill all the 20 guard in the game. you need to move to the sequence 7 of memory 3. You should not start the memory instead you should move to the past behind the Arch and simply hire a COURTESANS. They will help you to hide yourself in the game, now walk to the past near the guard arch and one step left to the walk back to the arena. You need to do this all these thing until and unless you have killed the 20 guard in the game.
