You can set the campaign on low and fly through the (provided you are not going for any other campaign achievements with this one) campaign in about 4-5 hours.
Do not touch any boosters (health or reflex boosters). Sometimes the game decides it will automatically pickup items for you if you're too close. I avoided them like the plague, never even daring to get close.
Also you have to be careful -- if you do happen to pick up a boost by accident IMMEDIATELY exit to the dashboard. The game has a weird save/glitch where even if you didn't hit the check point it will still remember if you picked up a booster. Exiting to the dashboard will circumvent this problem.
