How to Play San Francisco Rush - Extreme Racing
Quick start
Choose the available race, check driving inputs and learn the opening bends. The SETUP menu reports that it is not yet available.

D-pad steers and selects; acceleration and other driving actions follow the prototype's layout. Use its available race/menu prompts and keep the road exit in view before turning.
San Francisco Rush - Extreme Racing — About this game
Begin with the available race and learn its steering response over a short stretch. Observe where a bend begins, then alter the entry line on the next run instead of changing every input at once. The prototype retains development information on screen and its SETUP option is not implemented, so explore the playable race as it stands.
