N.I.C.E. 2 Tune-Up is a Add-on for N.I.C.E. 2. It ships with all benefits from the patches for N.I.C.E. 2, especially an arcade mode and further optimisation for 3D graphic cards. Add-on exclusive content are six new courses in Canada and northern Italy and a new vehicle class with four German cars like the "Firewolf Turbo" with 400 hp. The rest consists of smaller changes like a random start position in duel races or bonus points for the fastest round.
