Do the SCP use GW-era craft, like the Leviathan?
The SCP uses FS1 era ships in a similar capacity to the GTVA. Some of the ships have been more heavily refitted though.
And why does the Golgotha only have 200k hitpoints? Guess I'm too used to having supercaps with hitpoints over 400k...
You answered your own question. Having supercaps and uberships does not necessarily mean good game design.
'nother EDIT:
What's the Babel Effect (campaign)?
A project of mine from quite a few years back, some plot elements of which appear in some sections of BWO.
Does Admiral Kepler have a big part in BWO?
Admiral Kepler's office refuses to discuss the degree of involvement that the good Admiral may or may not have with a supposed GTVI SOC squadron called "Blackwater" and their operations. Not that this squadron actually exists, it's purely rumor and speculation from the media.
