VR Mission 1.1
This is introduced as part of the mission but you can, in theory, miss it. After you come to your second Gekko battle, you'll bump into an Electromagnetic Barrier. To get by, you'll have to go through a building. You'll open a door using a switch. Inside this building, on the bottom floor is this VR terminal.
VR Mission 1.2
There will be a mini-boss fight with a Hammerhead Chopper. Following this, you'll find yourself back in the streets. There will be several enemies blocking the street and they'll have the Hostage amongst them. The VR Mission will be atop the building to the left of the hostage but to get there, you'll have to go further up the road and climb some shorter buildings first.
VR Mission 1.3
After getting through a giant gate which required an ID Chip (or good Blade Mode skills), you'll come to a fountain in front of a large building. You'll fight your first Armored Cyborg here. After the fight, you'll enter the building. Stay on the first floor and go up the hall ahead and to the right. At the end of the hall, turn left into a small hallway. The VR Mission is at the end of this hallway.
VR Mission 1.4
After exiting the last building in the area, you'll find yourself on a giant gas tank. There will be a catwalk with a set of stairs leading up to Mistral. Instead of going up to that fight, go down the stairs just to the left of these. On this lower level will be this VR Mission.
