You will be given a starter kit. Bank the starter gear and whatever else you need, if you don't want the rest of the items just ::empty them (optional)
After that, wear your gear and head to ::train and kill vortex for better gear.
After you get the wanted gear, I suggest heading to ::superman and grinding them for gear AND 2b Tickets.
Grind superman till you have a good amount of 2b Tickets.
Now with the 2b Tickets, you can purchase lamps to pace the leveling up process
That's the basic starter guide... For more information check out the forums and explore around a little bit.
