Its available for free(legally).
I found it straight away on the simplest of search terms(not that I want it), so you obviously didnt search hard enough or not at all.
So did i, and i found it. BUT i had to go through heaps of rubbish, sign up to some random sponser of this website and answer a question to access the link to downloading the game. Once i finished doing all that and downloaded the game - it wouldnt work because of some file missing..
I downloaded it twice on Limewire, but it wouldnt work because of security reasons and missing some wing.dll file...
