[b]This does not involve cheating or manipulating networks, consoles, ... in any way.[/b] This trick simply involves a single specific weapon perk. First off you will need a scout rifle with the shoot to loot perk, preferably with a high firerate. As far as I know you can only find this on green scout rifles, possibly blue ones too but I haven't found any yet. Either way it doesn't really matter as you will only need it for a few seconds. Basically what this perk does is you can shoot ammo to pick it up. Why is this so good? Because you can shoot ammo boxes multiple times before they disappear and get more ammo each time you hit it. This is why a fast firing scout rifle is recommended. Using this method, you can get 8 rockets per heavy ammo box and 4-5 from heavy ammo dropped from enemies. Note that you can't shoot the actual ammo box before it is opened, you must let your teammates open the box so you can shoot the actual purple ammo that drops on the ground. Shoot the ammo as fast and as many times as you can and you'll get 8 rockets every time. I have not tested this a lot on machineguns but it doesn't seem to be very effective, only giving a few extra bullets per shot. This method is extremely effective in Skirmish and Doubles because you generally have more time to switch guns, shoot the ammo, ... and you're pretty much invincible with 8 rockets in a 3v3 or 2v2. It's a little but tougher to pull of in Control or Clash because there's more enemies to prevent you from safely doing the trick but if you succeed you can get up to [b]24 rockets per game[/b] and that's just from 3 heavy ammo drops. This isn't including heavy dropped from enemies so you could get much than that. Sidenote: This is also helpful in PvE. If you see a purple ammo box simply switch your gun and get maximum heavy ammo from every purple ammo box. No need to use synths when you can use this instead.
