Speaking to CVG, Unreal Tournament 3 producer Jeff Morris revealed that they plan to ship 30 to 40 maps with UT3, a lot more than any other multiplayer shooter.
“We don’t know the exact number of maps we’ll ship with but we want it to be between 30 and 40 - that’s substantially more than other games in the genre.”
He added that there would also be “spectacular” exclusive content for each console,
“While we want all of the versions to be the same that’s not to say we won’t do exclusive patches for each platform and that would enable us to do some pretty spectacular exclusive content”
Epic is known to support their games very well, continuously releasing new and free content (like the new Gears of War maps recently released). They also show great interest in the PC modding community, ever since the original Unreal was released. It’ll be interesting to see what they can offer after UT3 is released.
