Cyberbots was made as a spiritual sequel to a beat'em up called "Armored Warriors". I've never known if Cyberbots is supposed to take place within the same world, but they share the same lead robot. It's available in the capcom beat'em up collection.

It's made by the person who created Rez for the PS2. Not as good, but still an enjoyable experimental title. Short and not too hard. en.wikipedia.org/wiki/Child_o...
