I'm Back to Walking Again
You are now alone in the room where the tram came to a crashing halt. Take some time to look around. There are several crates you can pull off of shelves with kinesis. Drop them on the ground and stomp on them to get what it inside. Pick up a power node and a schematic for a pulse rifle.
Check out the table by the ramp for some credits, and grab a small med pack from the locker. Then head up the ramp and stop at the save station to record your progress.
Head through the doorway near the save station. Make sure your weapons are all loaded. As you approach some corpses on the ground, one will rise up. The Slasher attacks you at close range, so try to shoot it as you back away; this will make it pause, giving you a chance to finish it off. Pick up a power node from a circuit box on the wall and grab some ammo from a locker, then follow the corridor to another door. Enter the next area.
The Shops Are Closed
As you exit into a shopping area, it seems quiet. However, as you look around, a new type of Necromorph attacks you: a Pack. These are easy to kill on their own. However, they come at you in a horde. Use the line gun to slide through several of them with a single shot. You can also use the javelin gun, electrifying the javelin after firing it into the middle of the group. Melee attack any that get in close, and try to back away from them as you are firing to give you some space and time.
After killing all of the Pack, pick up the ammo and other goodies they dropped and then headed toward the save station. Stross contacts you, so listen to what he says. After recording your progress, stop at the store to insert the schematics, which gives you access to new items. Purchase the pulse rifle so you now have four different weapons.
After making your purchases, head to the elevator and take it to the concourse mezzanine. Be ready to shoot the pack that is running away from you to get an item. Look around to find a text log and some credits.
Once you have picked up everything you can find, head into the Unitology section, where you will find another text log. Pick it up and then move over to the elevator. It is not working, so open the panel next to it and do some hacking. This will repair the elevator so you can now use it to reach the Unitology Resource Center.
As you step off the elevator, go to the counter and pick up a text log and some credits. Then continue around the corner. Don't go too far, since you have several Necromorphs headed in your direction—two Packs, a Slasher, and an Exploder. While you could take them all out individually, you can also back up until you are against the wall, then shoot at the glass behind them to cause a breach. As the area decompresses, the Necromorphs will be sucked out into space. By backing up against the wall, you give yourself the maximum amount of time to shoot the lockdown switch at the top to stop the decompression. Reload your weapons as a second wave of enemies are on the way.
More Pack will come out at you from all directions. Use the pulse rifle to shoot them as they approach, or use melee attacks when they get in close. Once they are all dead, search the area for credits and ammo, then open the access hatch and crawl through the tunnel to reach the next area.
Taking out the Garbage
Walk through this room and stomp on the four crates here to get some goodies. A video plays on a screen explaining how to use kinesis to pull off spikes from Slashers and launch them as weapons. If you have not done this already, practice on a corpse and then continue to the control room.
In the control room, you can use the workbench to upgrade your weapons and equipment as well as use the save station. Once you are done with these, walk over to the blue console and shut down the garbage compactor. Then search the locker before exiting this room.
As you leave the control room, stay at the ramp's top and get your line gun or javelin gun ready. A Puker and a couple Slashers will come toward you, and both of these weapons are great for damaging several enemies in a small area. There is also an Exploder, so be ready to hit it with stasis and dismember it, since you don't want its sack detonating so close to you. Once you have collected anything the Necromorphs left behind, head out into the Zero-G garbage compactor.
This large, open area has no gravity. Your suit has magnetic boots that will keep you attached to the platform. However, you can press the Zero-G Launch button to launch yourself into open space. Head to the platform to the left that is located under the control room. Press the Zero-G Launch button to reengage your boots. Enter the room to find some lockers and a circuit box with a power node inside.
Now exit the room and launch yourself across the open area to the platform on the opposite side. Head through the door and continue to the console at this room's far end. This controls the turbine in the garbage chute. Press the Action button while near the console to move the turbine farther down the chute and activate it.
Now head out into the open area and launch yourself into the air. Move into the garbage chute and dodge the debris as you travel through the chute. Press the Run button to fire thrusters in your boots, allowing you to move against the flow of air. Press the Alt-Fire button to orient yourself toward the ground. As you approach a platform on the right, move over to it. Press the Zero-G Launch button to magnetize your boots so you can stand on the platform. Now move through the doorway into the Cassini Towers Infrastructure.
As you enter the service corridor, the lights will go out. Stomp a couple of containers to get some items; then use kinesis to pick up a metal rod and carry it. When you get near the corridor's opposite end, a Slasher will jump out at you. Launch the metal rod at it and then finish it off with a weapon.
A power cell has been removed from its socket. Pick it up using kinesis and then maneuver it back into the socket. This will restore power to this corridor and to the elevator.
Before leaving this area, open the door to the storage room. It is power locked, so you will need a power node to unlock it. It is definitely worth it—inside are lots of credits, containers, a medium med pack, and a semiconductor. After you grab everything, head to the elevator, which will take you to the Cassini Towers.
The Cassini Towers
Upon exiting the elevator, get a power node from a circuit box on the left wall and then continue through the door into a hallway. An open apartment door lies directly ahead of you. As you approach to check it out, several Swarms come at you. Fire a grenade using the pulse rifle's alt-fire mode to blow up several, and then use automatic fire to clear out the rest. If any of them jump onto you, press the Action button to knock them off and kill them. Once the room is clear, move in and pick up some credits and a text log.
Continue down the hallway. As you approach the next open apartment, a Slasher will come after you, followed by several Swarm. Kill them all. As you hang back, the Swarm will usually stay in the room. This makes a great opportunity to fire in a timed mine from the line gun. When it blows up, bye-bye Swarm.
Continue to the third apartment. You will find some credits in the first bathroom. Head into the kid's room to find more credits. This apartment is clear, so once you have the credits, go through the doorway.
You are now back in a hallway. Head to the right to find an item you can use, and then head to the large door. Move across a walkway and go through another door into the east wing.
In this next hallway, as you walk over to the container to stomp on it, a Slasher bursts through the door. Hit it with a melee attack since you are close enough to move it away. Then let loose with a weapon of your choice to kill it. Once it is dead, make your way to the elevator and ride it down to the lower level.
Big Fight in the Main Hall
As you exit the elevator, record your progress at the save station. Then make sure all of your weapons are fully loaded. There is a big fight coming up.
In the main hall, a couple Infectors are turning the corpses of Unitologists into Necromorphs. Try to kill the Infectors as quickly as you can. However, you will need to worry about the other Necromorphs that are coming after you. A good tactic is to hit an Infector with Stasis as it is working on a corpse, then drop a line gun timed mine. Move on to the next Infector without waiting, as the explosion should take out both the Infector and the enemy it was working on.
Watch out for the Pukers and the Slashers. Both come at you quickly. This is a good time to use stasis. There is also an Exploder in the mix, so shoot its sack at a distance to blow it up and hopefully kill or at least damage nearby enemies. The line gun is an excellent weapon for this area, since you have several enemies coming at you at once. This will slice most Necromorphs in half. Also try deploying a timed mine next to an Infector just as it starts working on a corpse. The blast will usually kill the Infector as well as the transforming corpse.
The javelin gun also comes in handy. Fire it at a corpse or at the Infector on the corpse and then electrify it. This will greatly damage both enemies. Keep up the carnage. If you have not killed the Infectors before they infect all the corpses, they will come after you once their work is done.
When the main hall is calm, walk around and pick up ammo and credits dropped by the Necromorphs. There is also a schematic for javelin spears here, so be sure to get it. Then exit through the large ornate doors at the rear of the main hall.
You find yourself in an instructional hall with several displays. To find out more about Unitology, press the Action button next to each display and listen to the information. When you have learned all about this religion, exit through the large doors at the hall's end.
Climb up the stairs to reach the entrance to the Unitology church. However, the military is already there, and a gunship is firing into the area. Notice that the enemy fire is falling near the center of the entrance area. As soon as you reach the top of the stairs, turn right and move along the right edge of this large room. Run until you reach the large doors at the opposite end. Rush into the church to get away from the gunship.
