Complete the ''Find Out The Truth'' challenge. Another way is to go to Fox Creek, jump through the fence, across the canyon, and into the ghost town. Stop at the church and bunny hop into the graveyard (hold Clutch, Rev Motor, Preload suspension, hold Back, release Clutch and Preload when the suspension is loaded to the max). Jump on the lower roof over the doorway of the first shop and jump from roof to roof until you reach the end. Jump to the back of the building's roofs that you were just on. The last ramp will lead you to a rock and a bridge (very difficult to land). Jump from the bridge down to the entrance to an open mine shaft. Continue down the path into the military base and down to Sal's spaceship. Run past the ship to the room where Sal is being held in suspended animation.
