Strafe side to side or a circular motion to dodge the shot's with out using your knock down shield. {this is what I normally do when downed and I don't put up a knockdown shield}
Nothing is more funnier then being a moving downed target and watching your enemies miss at a distance or up close. while watching them miss shot after shot and emptying a mag and having to reload or trying to punch you.
Then they are the one's being engaged by another team or your teammate while they're focusing in on you. And they get knocked down / Eliminated while your other teammate picks you up.
lol, hope this Tip helps.
** Side note this does take a little practice to master, but funny when you can do it.**
