No, there are no vehicles (there's only one car in one of the cutsceens and parked vehicles on the street witch you can't use). The game is a bit old but, as I said, I like it because it's easy to edit (it's really flexible). I was thinking to edit a few textures / sounds tomorrow in Jazz style and see how it looks (but I can't get as far as models).

Another bad thing is that the game has no ambient music (just some songs playing from some apartments or radios around the map) and when the characters talk their mouth doesn't move. And another thing (and this is a really big problem) is that if you shoot someone with the shotgun or other heavy weapons you rip their leg, arm or head off and it's not a really good image. And if you use some weapons like an upgraded pistol and you shoot someone in the head the whole character turns into gibs and spreads itself all over the street (I'm saying this because there's NO WAY I want to see something like this in Jazz (again, NO WAY (and for the third time, NO WAY))). And it also has pain skins if you hit somebody (this option can be deactivated from the menu though and can be removed by using the same bmp on "normal skin" and "pain skin").

Anyway, with the right software, you could get almost everything you want from Kingpin. Yes... tomorrow I'm going to edit a few textures and see what I come up with because I'm sure that this game would do the best Jazz Jackrabbit 3 if edited properly.
