There are an abundant number of excellent guides for the Eternity Vault so I felt it would be redundant to do another. Instead, I’ll offer some tips and tricks you can use to make things a little easier for you on your runs. These are very simple ideas you may find useful if you are having difficulty on certain fights. You may also find a ‘clever use of environment or mechanics’ usage here and there. http://corellianrun.com/2012/04/13/operation-information-eternity-vault-tips-and-tricks/
I personally love the trick on how to get by those damn chirping dogs.
