Kill 3 enemies with the Longbow within 10 seconds
How To: This achievement is very hard, as it recquires expert aiming and the right opportunity. A good map for this is pvk_siege_longship_beta6. As an archer, go to the window to the castle door's right. There, you should be able to shoot at the vikings that are trying to break in. With some skill and help from fellow archers, you'll be able to shoot 3 down in 10 seconds. Also, although crossbow kills don't count, kills made with the longbow special does, so if you can find a large crowd of enemies, launch the special into their midst. You'll probably get 1 to 2 kills with the special, and then you can shoot down anyone who's weakened but not dead.
