With Nightblade, we're opting for an open development model where anyone can download and test the game as it is being created. This has a number of advantages over the traditional monolithic release some years down the line. We hope to benefit from the extra input and create a more polished, balanced game, while also growing our community of players and developers.
If you wish to help us out by giving feedback, then sign up to our forums, make sure you have UT3 installed, then download and install the latest alpha release.
