User blog comment:Sefranek/Solo Craw challenge.../@comment-4398083-20120617042828

All of my Craw kills have been solo, or a LAN game using Alt-Tab between characters (mainly for ammo regeneration support). The kills were consumated from the front by using either a Leviathan or a Jackal. Timing of shots is kind of tricky, but it can be done. Haven't had any luck with ricochet weapons.
