Instructions
Play though the game until "The Candidate" mission is made available. "The Candidate" opens after you complete the "Defend Bucky" mission. Head to the marker on your map between the hours of eight in the morning and 6:30 in the evening to start the mission.
Run to the auditorium, which is marked on your map, as soon as Ernest asks you to meet him there. You fail the mission and must try again if the timer reaches zero.
Stand on the glowing marker once inside the auditorium. You automatically enter manual aiming mode and take out a slingshot.
Watch your radar for moving red dots. These dots represent jocks that are coming to ruin Ernest's speech. Jocks appear on the catwalk, in the aisles and behind the stage. The mission ends if too many of them hit Ernest. Look at Ernest's health bar to see his remaining energy.
Press "Up" on the directional pad to zoom in, allowing you to see the jocks better. Hold down "R1" to charge the slingshot and then release the button to fire at a jock. Tap "R1" to fire quickly if you don't have time to charge a shot. Defeat all the jocks to complete the mission.
Return to your dorm, located by the front gate of the school. Head upstairs into your room. The "Halloween" mission will begin.
