It is not frozen enemy, you have to kill the enemy in freezing areas, meaning outside in the snowy areas. Just play Ice Gauntlet, Dom or Conquest and kill enemies outside, I already got 47/100 kills.
Oh it says on Freezing enemies. I think they describe them terribly. Thanks, just got 16 in a round after doing this.
Like others I am struggling with this (on 34 at the moment) -- I know it is on freezing enemies, but how do you know they are freezing ???
100 kills is just daft.....
Ice Lock challenge finishes tomorrow anyway.....
