I've been asked many times the same thing:
The answer is: I'm nearly sure. I can't say I will, because I've other projects in mind (all them related to UT, though).
Today I've worked a bit on the Phoenix... The flames are more realistic, I've done a decal code (sounds weird, but works preety well, removing the laggy excess of decals in the same area).
Also, I had a great idea in mind. Jetpacks? Yeah! I've done a part of it, it's fine, but I'll do a better thing later. You'll use it by trying to crouch in middle-air... Leaving a smoke trail. After I finish it, I'll post some screenshots... see ya!
