Getting Started
Here's a few things that're good to ease you into playing inferno. There's a lot of customisation in inferno, but you don't need to rush to specify everything about yourself immediately. As long as you have a basic description you can get to playing and flesh out more and more details as you go.
First give your character a description and maybe an outfit or two.(help editing, help creating)
Try your hand at combat by heading to your faction base and entering a warren.(help warren, help combat)
Look for RP either in your faction base or by using the where command and heading to where people are gathered. You can also use the IC command fsay to talk to others in your faction, come up with an IC way to suggest that you're new in town and would like some introduction.(help travel, help roleplaying)
Use the time spent traveling to set up your character, working on objects, outfits, rooms, cars etc.
Set up some custom attacks and make yourself a house.
