I'm loving a lot of these achievement ideas... There's only one I really don't like in the approved achievments and that is
BOOM, HEADSHOT!!! .... please come up with a better name for it, it doesn't fit, it has nothing to do with bond and it's not very imaginative either, the icon isn't in league with the others too.
Some of the achievements are way way too demanding aswell...
100/500/750 kills with a specific weapon is a little ridiculous... mainly the leap between 100 and 500... especially considering people's progress on the achievements will be reset when a new version of the mod is released (correct me if I'm wrong).
100/250/500 would be more appropriate in my opinion.
