what is EP4 about?

[Altavista]

Blue Burst only episode. Its a patch to the normal Ep1&2 i think.

No, it's a side new episode covering some bits to explain some mysteries of Episode 1 (who was the girl you rescued during that quest with Bernie?), Episode 2 (what the heck was Graham researching besides the Mother Plan in those towers?) and Episode 3 (how the heck did they create those cards? What with?).
It has a storyline of its own and it would be really pretty long to write it all there.
