Apparently they used the same engine for all their UE3 games back then. I've updated specific build in
this topic, now it should work with this game as well. Most materials will not be linked to static meshes as usual. Also, you need to choose appropriate compression method based on platform - zlib for PS3 version (should be detected automatically though, if platform option is set) or lzx for Xbox360 version.
Specific build is renamed to "grasshopper", since it now supports most of their UE3 games.
