Truck Jam, the most real Off-Road Truck racing game, is here for Mac OSX.
No Rules and No Boundaries, racing is pure fun. Find yourself behind the wheels of off-road trucks and play with realistic but most enjoyable controls.
Don't look for boundaries like in other racing games. Truck Jam doesn't limit the area. You can really drive as far as you wish across the varied terrains without any limitations.
You can also listen to numerous licensed rock tracks during the intense races.
