Note: If you want to get the Unstoppable trophy, which is for finishing the game on Expert difficulty, then go into the options menu and change it to Expert as soon as you get control of Delsin. You can also set it to Expert, then start a New Game.
The game opens up with a cutscene and once you gain control of Delsin, you’ll be in charge of doing a little bit of graffiti. You will need to turn the controller sideways, and then shake it as if it was a real can of spraypaint. What you need to do is spray in the stencil areas with the R2 button. The first color is white and there’s quite a bit, so keep spraying until it moves to another stencil with black paint.
When you’re finished, there will be another cutscene and you’ll have to escape through the back door. The path to the longhouse is fairly linear, so you won’t really need directions to get there. At the longhouse, yet another cutscene will play out, which will bring an end to this mission and automatically start the next.
