There is a new First Person Shooter game design program coming out September 22.
From the video preview on the website it looks like it creates a decent play experience.
It supports online multi-player mode.
It is about the same price as UT2004 but the games/maps you create can be distributed without additional cost. This makes it very attractive for our educational gaming applications. I bought a copy to investigate. We'll have to see how easy it is to import textures.
Anyone else interested?
Thanks to Cory for the link.
