General info on playing Freelancer?
1. Wrecks
At some point, you'll come across a wreck. They show up as red crosses on your nav map. Wrecks are highly useful, some contain good weapons, others contain valuable cargo, some a combination. If you want to find wrecks on your own, without looking them up, remember that they are wrecks - ie destroyed. So don't search open space, look in asteroid fields, gas clouds, radioactive zones etc.
2. Hidden bases/jumpholes
There are a load of secret bases and jumpholes in this game that many players miss. I, for one, discovered a new base about a month ago, having played the game for over a year. Again, if you don't want to look them up, remember that they're designed to be hidden. Look again in gas clouds and asteroid fields. A good way to find them is to turn on "Patrol Routes" in your Nav Map. Where you see a number of routes join, that's most likely a base/hole
3. Best ship/loadout
If you look in the various forums, you'll find many threads about the best ship/best weapon config. The loadout threads can be helpful if you're just looking for a set, but I urge you to experiment and find the best combination of weapons for your playing style. As for the best ship threads, ignore them. 99% of the time they're a load of trash, because everyone plays differently.
4. Trading
If you want to get some money via trading, search the spoiler forum for "Trade Routes". There are a lot of threads where people have posted the routes they find most profitable, you're bound to find one you can do easily.
Have fun
