Crysis 3 Walkthrough Part 4 – Post-Human: Infiltrate The Liberty Dome (Reactor Room)
Inside the Reactor Room take a moment to mark the 8 Guards that move around here. You have Troopers but also CBRN Units. Move over to the right and wait for the nearby Guard to come close by. Cloak and get a Stealth Kill on him. This frees up the area you can move around liberally. Still you need to be wary of what is going on.
Before dealing with the rest there is some Intel to find and some ammo to collect. Head down the passage on the right-hand side of the room. Any time you cross a doorway, cloak, to avoid being detected. At the very end of the hallway the Prophet will find the aforementioned Intel and ammo, if any stocks are getting low. Now just head over to the nearby doorway. There are only 2 guards you really need to worry about here. The rest can be avoided by virtue of the path here.
Start by picking off the guard on the bridge in the middle of the room. Take a little time to make sure he is between the railing and the crates to ensure there is little chance his corpse will be spotted. Now, look to the far side of the room. Pick off the guard there as well. Now, cloak and cross the bridge and get into the Robotics lab. Inside here, use the visor to find the next piece of Intel. After that just head on through, in a crouch to the next hallway.
It is time to deal with another big room with a lot of troops and CBRN inside it. To start out getting across there are 2 troopers on the side you are on. Move to each in turn and kill them with a Stealth Kill or an arrow. Now head over to the left and look to the left. There is a guard patrolling along that side of the room. While he is stopped, or you have a clear shot while he is closer to you, pick him off. Head over there and get to the top of the staircase. Move to the left and look down. You will see a CBRN to pick off. Cloak and head down after you do, if only to get your arrow back.
At this point you can, with fair ease, slip through the rest of the troop and get into the walkway opposite where you came in. Just head on through the hallway. If you need more arrows then make a break over to the right. There you will find an arrow cache. These are few and far between so put them to good use when you do find them.
Head toward the marker now and open the door with the panel to the left of it. Immediately cloak and down the hallway. There are 2 guards which you can ignore but there is also a Sentry Turret behind them. Head over to the left of the turret, cloak and use the visor to hack it. This will turn it against the soldiers and let you get through without any trouble at all. That or just bypass it completely and head over to the right. Get to the door and wait for Psycho to work his magic.
Once you get through, switch on your visor and look at the man on the right. He has some Intel on him. Grab it then follow Psycho into the elevator. This will lead you into the next chapter.
