button sequence

You would like to:
In multiplayer perform a sequence of buttons to make an assasination? … I mean, at the precise moment you hit the back of the enemy, think fast and pressing buttons on the screen to complete the assasination.
This same form also execute a sequence also random buttons to prevent being killed …

I thought ,because I’m a player who wants to participate in every moment of their actions when I’m playing.

and I think that would test our reflexes.

It would have to be very quick or you’d be left vulnerable to enemy fire for quite some time.

Nope. I’d rather just hit melee and be done with it. Be as quick and efficient as possible so I can move on to the next target or head for cover.
