Trophy Description:Kill 5 enemies with Rocket Launcher.
Trophy Type:Bronze
There's two different methods to go about doing this trophy. Its suggested that you use method 1 as it's the fastest and easiest of the two.

Method 1:
: You must be signed into the Sony Entertainment Network to unlock this trophy.
Maximum Players Needed to Boost: At least 2

Save your time and boost this in a Dispatch's Biohazard Mode Match, which is the only map this trophy can be acquired on. Once the match starts, run around looking for the weapon locker case with the Rocket Launcher inside it. If you're on the Spec Ops team, it's much easier to locate. When you spawn, just run to the right side of the area and up the platform to find a weapon case. Shoot the locks off it and grab the rocket launcher and run around killing 5 zombies with it. Make sure they're grouped together before shooting them. You have a total of three shots and the trophy will unlock on the fifth kill. If you need boosting partners, then please refer to the Trophy Boosting Thread. Remember to seek a boosting partner who has the DLC pack(s) that you're currently boosting.


How to boost killing 5 enemies with Rocket Launcher:

Have at least one boosting partner ready to accept an invite.
Start a Private match on Heroes and invite your boosting partner.
Select the Stage map called Dispatch. If you don't see it, then back out and remake the lobby (it could also mean that your partner doesn't have the DLC.)
Once the match starts, locate the Rocket Launcher inside a weapon locker case.
Run around and killing groups of zombies with the 3 rounds you have.


Method 2: This the same trophy description of Ticket to the Gun Show from the first DLC

This trophy can only be obtained on the third mission, "I Now Know Why You Cry." As the description says, it can only be done with the Demolitions Expert, Tweed. The door to the Foundry is actually a secret locked room with weapons, supplies and even a Rocket Launcher (Rocket Launcher is also related to the DLC Pack 2.) To get it open though, you'll need to use the C4 you can find in the mission to blow it open. Once you get one, you can hold on to it and just use Nemesis to open the gates/sewers for you. The C4 can be found in the following locations:

Nemesis first location found by the ammo refill crate
Next to the crashed helicopter that Nemesis shot down in the park

During the course of the mission, you'll encounter Nemesis with his Rocket Launcher. From here, you'll have to use Nemesis to blow up the gates after you found and picked up one of the C4s. Continue using Nemesis to blow off the gates and enter the sewers. Once in the sewers, fight your way down the tunnels until you made it to the Foundry area. In the Foundry area, kill the zombies and go to the far end to find the "door in Foundry" that the trophy description wants Tweed to blow up. Plant the C4 on the gates if you still have it on you and you'll blow it open. The trophy will unlock while you're checking out the goodies in the room.
