General Beginners Guides
A collection of youtube casts from Pandemic Horde.
It is split into two parts:
Firstly, a series of 10 videos going through the basics of Eve. Starts as if a new player had just logged on and goes through it all. Also includes some quick guides for flying in null sec and Asteroid Belt Ratting in null sec.
Secondly, there is a series of Pandemic Horde Lectures which includes a talk on Industry by Steve Ronuken as well as a lecture on surviving in Low Sec.
All good stuff and ideal for those just starting or those thinking about heading into Low / Null Sec.
