Multiplayer: Heavy Fire Support-15
Fire 1000 bullets in a round (awarded at end of round)
Choose Either a Rifleman or Special Ops. Now use any Automatic weapon, and fire as much as you can in a single game. If you run out of ammo, run to an ammo box to pick up extra magazines. This should come naturally to you, but if you are having troubles follow this method.
Choose an Automatic weapon. Find an ammo box. Keep shooting your gun until you run out of ammo. Pick up more ammo from the ammo box and keep shooting!
Well, my cousin did exactly as it says from the guide and it worked. :mellow:seems so simple but i still have yet to get it. i just sat next to an ammo box and shot 1000 bullets without dying. then ran around playing as usual. still no achievement. =/
This one was rather easy to get. Just keep firing until the end of the round. You might be miscalculating and stopping short.
I got it in my first try...just start a sector control or combat battle, and pick the assault class. Choose the M60; if you have the extra ammo thing use that. Just fire bullets into a wall the whole game; when you run out of ammo, go let someone kill you.
