In Brotherhood Ubisoft invented this nice combat that you can kill the enemies next to you if you once killed an enemy, as long as nobody hits you.
During this kill streaks, you can also perform a hidden gun kill or knife kill by holding left mouse button for about a second, and see: Ezio kills the enemy next to him and shoots a knife (with short blades) or with his gun (usual blades) to another enemy.
The good thing about this was not only that you can kill two enemies at the same time; as long as you perform this shooting combat streaks you can't even get hit by your enemies.
Does anybody got performed this in Revelations? I can't perform it by holding left mouse button, even if I have selected hidden gun or knifes as my secondary weapon.
It seems Ubisoft has removed this a bit overpowered invention; bad idea because I really liked it and once you've discovered it, it really helps you during combat. In the Training Program of Brotherhood I got a kill streak with about 35 kills on this way.
Thanks in advance for any help!
