In multiplayer when you get downed it has a heart pumping and tells you to press "A" does this actually let you revive yourself? or does it just keep your hart pumping till someone can get you?

There have been several occasions where I got back up on my own after speeding up my heartbeat. I dont really know for sure what goes on during these sequences so any info would be great.

multiplayer games have a bleedout time, usually 20 seconds, that shortens the bleedout time, reviving your self faster. if you dont press it you will just revive after 20 seconds.... unless you are revived by a team mate, or even better, cut in half with a chain saw!

You cant revive yourself in Warzone only Execution. It depends how you are killed to, like hamwbone said every host has a specific bleed out time already set, most of them are set to 20 seconds. Tapping A in Warzone doesnt help you revive only in Execution it will help you.

Tapping A in Warzone only slows your time to die giving your team mates more time to come save your down'ed ass.

cool, i havnt even played war zone yet, having to much fun with execution!

Alright, thanks alot guys. . . let us continue to play!
