One thing i saw onthe trailler was the wall breaking .... it's a good idea if during the combat we could break the walls.......
Other,
Huge arenas... other thing i saw was it... imagine a 3D combat almost without space limits ......
Other,
Arena fatalities.. i saw spike cilinders spinning around... i think that traps and hazards
would turn the combat more espectacular and unpredictable.....!!
What do you think of that ???
