Overview
There’s a secret mission in SR2 available as soon as you complete the “Appointed Defender” prologue mission. It ties into the first game’s events and you get $30000 for completing it, so it’s pretty useful early on.
Unlock Instructions
1. Go to Precint 31 (the police station you visit(ed) during the “Assaut On Precint 31” mission from the Sons Of Samedi arc);
2. Climb to the third floor, go inside the Detective Bureau and listen to the 3 recordings marked by the 3 floating Saints symbols;
3. After listening to the recordings, go to the room on the right (if facing the door from the inside the Detective bureau room), activate the 4th floating Saints symbol in order to read Jullius’ file;
4. Check your phone, Dex’s number has been added to your address book. Call him.
5. Go to the old Saints’ church, the one in the Ultor district that has been renovated and it’s used as a tourist attraction.
6. Once you’re there, activate the floating Ultor symbol in order to start the mission.
The game will take it from here, you’ll have regular objectives and so on. Note that you’ll be facing Masako troops, so it’s a good idea to have lots of ammo and grenades on you.
