Netrek is a free online multiplayer game that is played in a galaxy not so far away. Up to 16 players, from around the world, are divided into two teams representing the Empires that battle in space for dominion over the galaxy. To win, you and your team must claim the other teams space by taking their planets. Think that sounds easy? Think again, since you are always teaming up with different people as well as playing against different people, there is always a challenge.
