This news is a little late, but i would like to get Tribes2 out of the shadows and more in the public eye, as it is the best game i have ever played. The engine is damn sweet, and it is a game that you should run down to your store and buy now! Its not the easiest to get into, but if you enjoy a good challenge, T2 is for you!
The news - The official Tribes2 Shifter mod has released Shifter Server pack 0055d, which is available here -
You can also get the Shifter 2.4 Client pack from here -
If you have Tribes 2 - this is a must, as it is the best mod around :D
