I can't kill the first of 2 guards in Damascus rich district informer 1 memory strand without attracting guards. Is there some trick to this?
I am using hidden blade high profile stealth kill. Should I be using some other method? Do I wait for the guards to leave the area? That would be difficult because you only have 3 minutes to kill these 2 guards. I am playing on XBOX 360.

First you should be in low profile. Also, if you see that the abstergo logo in the top left corner has a red flashing dot, BLEND NOW. Do NOT strike untill the dot stops. Also if you do mess up, don't kill the guards who chase you untill you are far away from the stop. Try not to leave any bodies because that will cause attetion too. If that doesn't work, try the other guard then go back.
