Next, talk to Wrench again and access the 3D printer and get the default handgun. Print the Jumper as well. For now your priority is to save up enough money to get the quadcopter. It will be very essential for the entire game.
After getting the jumper, you can deploy it and have it enter the vent beside the lockers to get a new weapon Paint Job. You can’t go further yet since you don’t have the Access Key for this lock yet. After getting the quadcopter later on, you can deploy it inside the Hackerspace and retrieve the Access Key from the vent near the Follower Wall.
