Did you play in Counter-Strike with GunGame mode? In this mod you begin game with pistol and get better gun after every three kills. My idea is such race type. All players spawn in one world with MrWhoopie(or Infernus) and get better(or worse) car after every CP. There is single CP for all players, and when one of them pass this CP it change its position to random but on same locality (for example random point on SF Arport). Wins first player who get Infernus(MrWhoopie).
P.S. Sorry for my English. I hope you understand me.
