Unreal Tournament’s weekly builds are now available to anyone, not just developers.
The new Unreal Tournament is being developed openly and collaboratively. As part of this experiment, Epic Games has opened its weekly builds to anyone who registers on its forums.
You may recall these builds popping up back in August, but this is the first time they’ve been made available to anybody with an email address rather than just developers. You can access them through the pre-alpha build thread.
According to games.on.net, builds are available for Linux, Mac and 32-bit and 64-bit Windows, and there are even server builds available. The download is about 1 GB.
