    Kill 30 aliens with headshots

    This is easiest to do using the Railgun (a scoped 'sniper' weapon). A good area for increasing the headshot count is Highway Battle: Part 2 as there are plenty of sniper ammo in the area. The pigs also like to go for the turret which should help keep them still for an easy shot. The Pistol/Golden Gun can also be used for this.
