Rewards: 1500 XP, 10 tokens
The mission will be unlocked after getting access to the FNSM app. Swipe your finger left on the touchpad and select this quest to start the mission. Go see Teo in the Harlem district. He will let you know about the break-in at the store and ask you to find his cat. Follow the marker to a nearby power plant and enter the building through the window on the roof. Once inside, jump onto the opposite wall and follow the marker on the screen. Take out all enemies in the next room. Turn on emergency power with a Venom strike.
Teo's cat will appear and escape through the elevator shaft. Hold L1 R1 to turn the gear. Then, quickly aim (L2) and fire the Web-Shooter at it several times (R1). Then enter the shaft. When inside, zip down on the web and jump into the ventilation shaft. Eliminate all enemies in the next room and keep going forward, still following the marker on the screen.
You will reach another room with a group of thugs inside. Once you've killed them, use the Venom Punch on the breaker again to restore power. Follow the marker to the next room and get rid of your opponents. Look for the main generator (R3) and go to the power switch (1). It will not work. Connect two relays (2 and 3) with your web and then turn on the generator (4). When you approach the switch again, new enemies will appear. After winning the fight, take the backpack with the cat in it and flip the breaker. Follow the marker to exit the building and return to Teo.
