Stay tuned to the faction chats and Discord chats, follow instructions, and just have fun!!! You'll pound some people and get pounded by others. Use it as an opportunity to learn. Learn how to turtle, self-hosp, manage drug and med cooldowns, etc. but also try to learn and get into group attacks if they're coordinated.
Best of luck Kingpin!...You'll do fine! Just be loud in you Discord if you need to be. They all have/should have helpers to point you in the correct direction if needed when/if you have questions.
