Crisis Core: Final Fantasy VII/05: Where Are You?

This chapter starts in the Shinra Tower at the SOLDIER Floor. This is the also the chapter where you finish the first DMW reels and start the second.

SOLDIER floor
When you take control of Zack, you will receive new missions. Then, go to the Training Room for a side quest.

The Training Room
You need to beat 4 opponents in a row by doing more squats than them, in order to go faster, press the button only when Zack is down. For each opponent beaten, you will get an item for the Wagons Side Quest.

The Briefing Room
Don't forget to interact with the Supply Pod to receive the Fira materia. Then, go to the elevator, if you want, you can go to the Director's Office Floor to have an interesting talk with him.

First floor
If you came from upstairs, talk to the guard patrolling to receive a new set of missions. Don't forget to grab your free Raise by talking to the woman near the exit. But, also talk to a man in the center of the room, he will give you a new set of missions (do the first one to get access to a new shop). If you finished every missions from M2-1-1 to M2-1-5, go in the Exhibition Room and talk to the Scientist there to receive a new mission (M2-1-6, do it now, and go back to the Exhibition Room to talk with the Scientist. You will receive Mithril Tools (important for the Wagons Sidequest).

Into the Slums
To get to the slums, you take the train from Sector 8. When you arrive, Tseng emerges from the church and tells you Aerith isn't there. A helicopter appears and you load up.

Upon the Reactor
The helicopter will crash in the mountains near Modeoheim, Zack's hometown. You and a 3rd class SOLDIER will be ahead of Tseng and another 3rd class SOLDIER. You and him get into a discussion, bragging to Tseng how they are country boys. You ask for his name, and he takes off his helmet, saying Cloud. You gain Cloud's DMW reel. After hiking, you come to a reactor.

Reactor Invasion
Here, you have to invade the reactor. Watch, because you have to sneak around guards. There is also about six chests around the outside. You probably will not have done this before, but every time you're caught, you lose a chest. After all are gone, the guards leave. You go to the warehouse in the back and go in. You take the left track to get an item. You take the right path to come to a save point and an elevator. You save and come into battle, then take the elevator.

Genesis Battle
After taking the elevator, you see Hollander and Genesis arguing. Genesis will be gray in spots due to degradation. Zack will run in and stops them. Hollander's stupidity will draw him to get past you to Genesis. Hollander decides to run, and Cloud appears chasing Hollander. You go into battle with Genesis. The best way to defeat Genesis is to have these attached: Dark Fire, Dark Blizzard, Dark Thunder, Blizzara Blade, MBarrier, Cure Use the Dark attacks to hopefully poison Genesis and use Blizzara Blade to eventually wipe him out. Getting Aerith's DMW lined up will make you invincible for a short time. After winning the battle, Genesis will throw himself over the ledge.
