You have unlimited ammo during this mission. After the following cut-scenes, you will be thrown straight into a bank heist with Johnny Gat, Shaundi and actor, Josh Birk. The game begins with a Star Wars styled introduction to Stilwater, the Third Street Saints and the happenings since the previous game. Once you have obtained one of the two achievements, load the save and obtain the other achievement. In order to obtain both achievements without starting a new save, you should create a save before the mission (or within the mission). Note that at the end of Act 1, in the mission 'The Belgian Problem', the two choices each give you an achievement. Whilst respect is rewarded for almost all missions, this is not shown in the walkthrough as it is difficult to quantify unless stated, as with Assassinations and Vehicle Thefts. In these cases, the rewards for each decision are shown clearly. Several of the missions allow you to make a decision. All rewards that can be gained through the missions are also shown. This also includes story-related activities. The story walkthrough will tell you the basics to each mission.
On harder difficulties, you are generally faced with more enemies with better accuracy and more health, whilst you are more susceptible to damage. This walkthrough will guide you through the game as if you are playing on Casual difficulty. The difficulty can be changed at any time by pressing Start and selecting 'Difficulty' from the pause menu. If you want to complete the game as quickly as possible, select 'Casual'. The game is not that difficult, especially when you begin earning money to purchase many of the upgrades, so choose whichever difficulty you think will be most enjoyable. To begin the game, select 'Campaign' from the title screen and choose 'New Game'.
