It's in the cloud where the gate to sigma-13 is. And no, there aren't any planets in Sigma-13.

strafe! the three VHF's are equal in strength
You wouldn't use a cucumber to chop a tomato!

Several SP & scores of hours MP still finding new things. How about the BS wreck in Leeds near hole. The loot in Grande Negra in Texas, hear about it in rumor. Planet Harris is mentioned in SP story by Tobias. Just recently found the Britonia prison surounded by mines, what a bugger to get to/from. At least there is a path unlike the Molly base.

Yes, there is a plethora which can be found if one takes time to look for them.

It is hard to fly with turkeys when you soar with eagles.

I can quite confidently say, that after flying grid like patrol paths through every nebula, I've found everything in Freelancer!

Its a mazing to see what u think u knew. i have never seen BPI before in my hole freeelancing life and it just amazes me to find the base somewhere isolated. Makes me happy for finding stuff i thought i knew.

I think that the unknown object in Tau-37 is a spawn point for the rings around the sun, a bit like the rock near the dresden jump hole in Frankfurt and the invisible fuchu planetoid in Shikoku.

To get to that prison, look around for some wep plats and nav bouys.
WHERE IS THAT RESEARCH STATION IN KYUSHU?! I cant find it T_T
