[quote name='davey0110']is this a good game? i love unreal tournament, but i heard that the championship series is different[/QUOTE]
UC1 was basically a port of UT2003 with little changed.
UC2 was built for the ground up as an Xbox game and integrates melee combat among other things. It doesn't feel much like UT2004. For one, there's no Onsalught gametype.
It's a unique hybrid of a shooter game and a fighting game. It's one of those games you either love or hate. Personally, I like it. Most people couldn't get over the fact that it wasn't Halo 2 when it was released.
