I too heard of a go-karting place... I think is was listed on Shenzhenparty some time ago.. If you go there, and plug it in, you might find it... Or someone here will help you... I went paintballing last summer in Shekou. It's in a hotel right on the water (I will ask my friend the name for you) The area was quite small, but that makes for more "kills"... I'll get back to you, and I will keep watch here for others that may have more info.
