How do you get the sniper achievement?

[Callum]

I've got way over 77 sniper kills now and still don't have it?

Icon implies needs to be in snow levels?

It might even be bugged... says only 0.2% have it.

Thanks for the reply. I'm going to try only snow levels and if it doesn't work then I guess its bugged

it may only be headshots, i have it but it took ages even after getting the kills so try doing snow levels and headshots
