I am New on XBOX and I am having trouble with this game, On Operation Bravo Mission There is no place like AAHH Zomibes it says one of the sercerts is to Kill them before they Multply and I kill every zombie I see but it won't unlock if any could help that would be great

i randomly nuked zombie groups on the last trip back to base with rockets and i got it. you can also try to shoot a bit with the MG while dashing to the survivor locations and thin the undead population a bit.

but i think you have to kill not the single ones standing around, but the groups like in the beginning of the stage

it's probably something like "kill x within y seconds" cuz i nuked like 2 or 3 groups as i flew and got the "zombie crowds thinned out" thing along bottom of screen.

I got it yesterday. I believe it is just killing maybe 100+ zombies or something to that effect.
