Watchmen The End is Nigh Part 2

Throw an enemy far away from the others. While nite owl/rorschach takes care of the others you beat that one then repeat until you have it!

There is a spot in level 1 where you are on the catwalks above the strip club floor. Simply grab the enemies with B and toss them one at a time off the catwalks (careful not to do any damage to another enemy) instantly killing them. 10 or so and you're done, just keep at it and finish off any who didn't fall off before you grab another

update: didn't get it with this solution on a nite owl run but confident with this as a solution while playing rohrshach. Enemies too hard to throw with owl but if you go into rage mode with "shach" as you engage up there you can launch them easily

Did get it another way as Rohrshach in level 1 when you go under the gate the first time and split up with owl. Take the guy's bat when he ambushes you in the mirror room behind the stage at the strip club and use that thing to clean house (i spammed Y over and over). Keep ahold of it when owl lifts the second gate and you should have whacked enough guys to pop the cheevo by the time you get to the orange door you have to bust through

If your rorschach you should just walk up to a single foe that's not near sombody and press your rage charge move(RT) on the weaker bad guys one shot kill with this move now repeat 9 more times.If your night owl you should throw your foe away from the battle and do a 5 hit combo you should get it easy.
