"Here's a list with over 160 custom model released (or WIP) for UT3.

I take no credits for them. If you have any comments/questions regarding a model, you should post it in the model's own thread, because that's where the author will see it. However, feel free to leave a comment here as well. Help keeping this thread on the first page!"
