Where can you download Freelancer the game for Free for PC

Despite the fact that Freelancer is 10 years old and can be bought for as little as AU$6.95 (seen at EB Games store Melbourne, VIC. Australia), Microsoft have still to release the source code for developers to modify the engine completely and release it as a freeware game. This is typical of Microsoft as Freelancer has a massive online support and development community... they are still making money from the game.
