What's the difference?

the difference is in UC the different species of tournement participants have different physical abilities.for instance,a gen mo runs very fast but only has 70 health to start with,an anubin is almost acrobatic,starts with 85 health,and they get more out of adrenaline than the other races do; an automaton can dodge jump very far,and has 110 health to start with; nightmares regen health the more damage they inflict on their enemies,but start out with 70- health and are almost as slow as juggernauts; and juggernauts have a ridiculous amount of health but they are very slow.

i don't think there is a difference between the species in 2k3,just in how they look.there is a species mutator for 2k3 out,i forget what its called...makes 2k3 like UC,but with better resolution and textures.

playing UC and 2k3 with the species mutator really makes me see why epic nerfed the translocator in BR.as an automaton or genmo,you can grab the ball and score in seconds if your smooth enough.cheesy.
