As of October 30, 2009, Sonic.net has a public-facing Tradewars 2002 server running at tradewars.sonic.net. This is a stock Tradewars door as with the classic game, except it is accessed through SSH on port 22 and uses active Sonic.net username/password pairs for authentication.

TradeWars 2002

Trade Wars 2002 Game Server v1.03                          Copyright (C) 1998
www.tradewars.com                                   Epic Interactive Strategy

that's just the server, which can juggle multiple games. The game itself is version 3.13 gold

In TradeWars, the player takes on the role of a sci-fi merchant, exploring space, settling new planets, and trading between space stations. As a multiplayer game, players compete for resources and can communicate or conflict with each other. TradeWars provides no explicit goal; players may seek to amass wealth, control territory, battle rivals, and accrue experience points.

Tips

• Upon logging in, check for the location of Stardock by hitting 'v' at the command prompt. Stardock is where you can purchase upgrades like long-range scanners, genesis torpedoes to make new planets, trade in your ship for a different model, and several other options.
• Be careful about attacking ports. They are rather likely to blow you up.
• When you log out, your ship remains in play wherever you left it. If you have a positive alignment (you are not a criminal in the game), you can park safely in any sector labeled as "Fedspace." Fedspace includes sectors 1-10 and the Stardock.
• By creating or joining a corporation, you can play cooperatively with other players.
