Nuked Out Tip

Use 2 classes. First class is gun with 6 attachments. Second class is 1 gear item and 6 perks.

Spawn in as class 1 with a specialist you don't want to play. Shoot your weapon once. This will lock you as that class and will not let you auto switch classes w/o dying. Then select class 2. Game will tell you "you will respawn as this class next time" Then, select the specialist you do want to play as. You will spawn in with your preferred specialist with class 2. If you did it fast enough, you will respawn in the same place (as all other spawns are taken by other players) and see your gun with 6 attachments on the ground. Then you go for your 30K.
