Sol - yeah, you've got the first edition.
The new edition consists of:
BPv2 Player's Guide - all the chargen stuff.
BPv2 Moderator's Guide - all the GM secrets and background. These two are the corebooks and are VERY chunky and chockfull of info.
Frontier Justice - life as a GEO Marshal
First Colony - Haven sourcebook
Fluid Mechanics - Equipment book
Natural Selection - Poseidon sourcebook
Ancient Echoes - Cetacean sourcebook
I don't have the first two so I can't comment on them, and Fluid Mechanics is a fairly standard tech book, but Natural Selection and Ancient Echoes are awesome. You won't find a more detailed description of a planetary environment and alien ecosystem than Natural Selection - if there were books like this for worlds in Traveller then it's just be amazing. Ancient Echoes provides some history for the Cetacean races and loads of stuff about psychology and outlook and cetacean-centred technologies - it's a great addition to the line.
Unfortunately, FFG dumped the line after letting it languish for ages
. Biohazard apparently now have the rights back, but I have no clue if they're going to do anything further with it. There were plans for an Incorporates book (Black Crusade) and an Earth/Solar System corebook (World of Hurt), but they've come to nothing so far.
But still, there's a lot of good stuff out there, so it's worth tracking down if you can find the new edition. You can get the first four supplements on the list above as a single pack for cheap too, so keep an eye out for that.
