I like the way they did the combat achievements on the 360. You can actually track them (ex Pin 10 enemies to the wall using the Hammerhead 4/10 ect...)
I find myself checking different weapon achievements before I run through a level or if I find a new gun. Then I will try to set myself up in a situation to finish it off.
Back to my earlier question: Is there a good use for the prototype weapon that shoots the big slow moving blue blob you get from Snake Fist? I shot it a couple of times and either A) I missed due to a cover issue, couldn't really tell B) Didn't seem to do anything to regular troops.
