Nitro Speed 2 Underground
Night-city street racing with a nitro boost, several modes and a free-roam city option.

The city is the star: wet asphalt, sodium lights and long avenues that let a car reach a speed the next junction will not forgive. Nitro is the tension in the design — it is exactly powerful enough to make you use it a corner too early.
Alongside the timed events there is a mode for simply driving around, and it is not filler. Learning where the roads open out is what makes the challenge events winnable later, and the city is pleasant enough to circle without a clock running.
Controls
Arrows or WASD to drive, shift for nitro, C to switch camera.

Frequently Asked Questions
Is there a free-drive mode in Nitro Speed 2 Underground?
Yes. A city mode lets you drive without a timer, which is the easiest way to learn the routes used by the timed events.
