Quick guide on how to get the "Epic Slam Dunk" Achievement on Trials Evolution (Origin of Pain DLC). Text Tutorial Below. Navigate to the "Paine Island" section of Single Player, and select "Skill Game Circus II". Start a game on "Uphill Struggle". From the spawn, drive up the first ramp, stopping near the top, and roll backwards. When you near the raft behind you, pick up the back wheel, and as it touches down of the ramp, hold Reverse. Then pick up the front wheel so that you are completely on the raft. Once you are on the platform, it will move backwards. Stay near the middle. Once it stops, you will roll backwards, Press and Hold Y, and you will perform a bailout, and grab the Basketball hanging from a rope. Continue to Hold Y, and the ball will fly you up and to the right. You have some control over your direction during this, so make sure you don't hit the side of the hills in the map, but don't go too far from the map either. Once you near the top, you will arc toward the Basketball goal. Land with the Ball in the hoop (hitting the inside of the rim while holding the ball will work), and you should get the Achievement.
