Many new features have been included in the game. New vehicles include bicycles (which feature a new control scheme), trucks with detachable trailers, police motorcycles, operable tow trucks, combine harvesters, quad bikes, aircrafts, military jet fighters and trains. A new activity that continues the Grand Theft Auto series' tradition of controversy is home invasion [1]. Under cover of night, CJ is able to sneak into a residence, and cart off valuables or shake down the occupants.
