After deciding which company to campaign for, using when in front of a non-player character will open up a window with campaign pitches. Depending upon their response, a certain number of points is added to a tally. A representative of the company can tell how many points have been accumulated. When enough points are made, the publicity level will go up.
If publicity level 5, which requires 400 points, is reached by Chapter 5, the player get an Episode Complete. The publicity level can only go one higher than the current chapter, so if 150 points, enough for level 3, is made in Chapter 1, the level will stay at level 2 until Chapter 2 is reached.
Another way to earn points is to play minigames for that company in the Calm Lands. If enough credits are spent, points will be added to the total.
There are a few rewards for completing the PR Mission. If level 3 is reached for a company, they will open a new mini-game to play. Open Air starts the "Gull Force" game and Argent opens the "Feed the Monkey" game. They also start selling new items depending upon the publicity level.
At level 5, after the integration, every item becomes available for that company. It is fully possible, though time-consuming, to earn enough points for both companies to reach Level 5. If the player switches companies, they will lose half of the points of the company they were campaigning for previously. It is possible to attain an Episode Complete by earning a tie, in which case a slightly different sequence will appear.
