    I have just unlocked this as of 20/08/2013.

    I played on 'Action Sack' playlist and selected the 'Rock 'n' Rail' game type. This game type spawns you with unlimited rockets and unlimited rail gun ammo.

    This achievement pops in game once you have achieved 4 kills with rockets without dying.

    I managed to unlock this achievement without purchasing the Bullseye DLC, whilst playing online with friends.

    As everyone uses rail guns and rockets, this can depend highly on the amount of skill you have. Though if you can fill the 8 spots needed for the 'Action Sack' playlist, you can boost this with little trouble to no trouble at all. You can use extra controllers or guest accounts. Meaning you could only need 2 people with 4 controllers.

    Good luck unlocking this achievement!

    This achievement can be difficult if not approached properly.

    ***The action sack method for rock and rail can be hard if you play with skilled opponets as they will jetpack and railgun you the whole match. Classic Fiesta is also hard becuase when ever i play it i get the rockect maybe once and getting 4 kills is difficult while getting shot at by incernation cannons and fuel rods.

    The simplest method would be to play an objective gametype that doesnt include vehicles. Use the ammo tactical package as this will give you an extra 2 rockects in case you miss. just wait near the objective such as your flag in ctf or wait for the ememy to cap the hill and fire away!

    I managed to get this on action snack but it was a fiesta flag game type. And as the map was a funnel both teams with a sightline to each flag and spawn point with only one route to and from; I just unloaded every time I got the rocket launcher.

    I actually managed to get it hanging out near the middle point in a alcove of sorts as they rushed I fired eventually netting 3 kills (with a shotty kill somewhere in the mid) my 4th I just fired towards the flag/spawn point and got a little lucky.

    The hard part is staying alive in this game type and getting into position. My initial thought to fire everything at the enemy flag for all 4 kills didn't work. I admit the power weapons were like rain drops but I was surprised when it unlocked as I didnt think it would unlock on something like this. Yay! :)

    Just another idea piggybacking on the action sack solution above.
