[quote name='Magus8472']Any of the crossbow guys in 2-1 should be easy for the knife bit. The ones around the dock would probably be best since they're far enough away that you'll have time to react to the bolt. Still, you can do it on a closer one if you're willing to have to anticipate the guy firing.
3-2 is best for the headshot. Jump down to the area in the middle and stand on one side of the large gap they all have to jump across to get to you. Aim up with a shotgun (the Ithaca is probably best if you have it upgraded) and fire as they're leaping across. Alternatively, on the same level you can wait at the edge of the platform you start on and wait for them to leap up the wall but you'll have to react a bit quicker. You can also try sniping them as they're jumping along the path to get at you but that's significantly harder.[/QUOTE]
I completed the jumping headshot achievement on 1-1. Stayed in the house and aim out the window using the Gatling gun when I was attempting to get the Gatling gun achievement.
Also, I've saved up a few eggs in anticipation of completing the egg duplication trick, but I'm finding that playing other difficulties and clearing the other achievements is giving me plenty of cash. I've already maxed out the starting firearms and the "best" firearms from upgrading the starting ones. As I complete Veteran (and beyond that Proffesional) I should get enough more than enough cash.
