Chapter 3: Walk-through
This section provides a walk-through for Deus Ex: Invisible War. Theres no single path through the game. There are many optional quests that can be completed or ignored. Additionally, nearly every situation can be solved in multiple ways. Suppose you encounter a security camera. You could hack a security computer to disable the camera, you could use a multitool to disable the camera, you could use an EMP grenade to disable the camera, you could use a weapon enhanced with an EMP converter to disable the camera, or you could just try and sneak past the camera.
This walk-through attempts to provide several possible solutions to many of the games situations but theres likely a different solution available that could allow you to still reach the eventual goal.
The walk-through attempts to point out the location of many food, health, weapons, credits, biomod canisters, and other key items. Thorough exploration is always encouraged above and beyond the walk-through as you will likely discover even more important items scattered around the game world.
Secondary goals are optional and you can chose to complete the side quests or ignore them. Many contain awards, such as credits or even biomod canisters, and are certainly worth the effort.
Note that characters you meet throughout the game can be killed, which can prevent them from appearing later in the game.
Approach the holocomm unit on the left desk and speak with Leila Nassif, director of the Tarsus Academy in Seattle.
Primary Goal: Tarsus Assault - Get Map.
Open crate in rear of apartment. Grab datacube to get map.
Primary Goal: Tarsus Assault - Meet Billie.
Before leaving grab binoculars and MontyBites! bar from the desk. Exit and grab some soy from the kitchen. Proceed left down the hall. A guard is killed by an explosion. Grab the partial clip left behind (may need to pick up his body). Move left at intersection to apartment 454. Use intercom on the left side of the door. Enter and talk to Billie Adams.
She provides the Elevator code.
Primary Goal: Tarsus Assault - Report to Dr. Nassif.
Talk to Billie Adams several times for additional information. Check the kitchen for food; there's some more soy in the fridge. Exit Billie's apartment and proceed to the elevator. Check the public news terminal on the left side of the hall before venturing to the elevator. Talk to the SSC guard next to the elevator then use the keypad on the right. Ride the elevator to Tarsus recreation.
Walk to the window on the left side and speak with Leila.
Primary Goal: Tarsus Assault - Meet Klara; Primary Goal: Tarsus Assault - Meet Leo.
Walk right to staircase but go left toward the water cooler. Find Klara here pacing back and forth. Speak with her. Go into the gym on the left and speak with Leo, who is running laps. After the conversation, Leila announces an emergency alert.
Primary Goal: Tarsus Assault - Get equipment.
Exit the upper level of the gym and go downstairs. Find the locker room on the far right. Leila will update the situation while you search the lockers; orders are to exit the facility. Grab the pistol, medkit, multitool and baton from your locker. Grab the ammo and food from the left locker. You can use the multitool to open one of the two right hand lockers for their equipment.
Primary Goal: Tarsus Assault - Exit the facility.
Exit the locker room. The SSC guard warns you of a seeker. You can help the guard or just avoid the seeker (inside the gym, hide behind the pillars on the right). Return to Leila's office and speak with Billie.
Primary Goal: Tarsus Assault - Go to Biomod Lab.
Billie suggests going back to your apartment and finding the breach that leads to a hidden Biomod lab. Enter and ascend elevator and return to Tarsus Apartments.
Exit the elevator and grab the stun prod, pistol, ammo, and flashbomb near the dead guard. Talk to the other guard; he'll ask for your help in taking out a seeker. If the seeker dies, pick up the ammo clip. Check out Klara and Leo's apartments for food, multitools, and read their messages. Use the vent shaft between apartments to find another multitool. Don't forget to open the storage crate. Check Billie's apartment again for any missed supplies. Return to your apartment.
Billie cuts the power, which exposes the roof and the ever-watching scientists. Check your fridge again for more soy then go through the hole in the bathroom. Climb down the ladder then climb up the far ledge as instructed. Enter the biomod laboratory.
Approach the rear of the lab and hear from Leila Nassif.
Primary Goal: Tarsus Assault - Install biomods.
Open the biomod screen and select your desired biomod. Search the lab for additional supplies and datacubes for information. Enter the next section and speak with the scientist; there's a camera and turret combo nearby that you must sneak past to avoid damage. Snag more supplies from the table--and hear again from Leila--before going through the door on the right.
Sneak past the camera along the left wall. There's an energy cell on the far right if you want to risk being detected. Ascend the stairs and speak with more scientists at the top. More terrorists are on the way.
Secondary Goal: Protect scientists.
Eliminate the two order seekers arriving from the staircase.
Secondary Goal: Collect reward.
After eliminating the seekers, speak with the scientists. One hands you a silencer weapon mod for your efforts. Search the lab. Grab the energy cell, read the datacube, and spot the black market biomod canister in the locked cabinet. Use a multitool or the explosive crate (shoot the crate when it's next to the cabinet) to open it and get the black market biomod.
To exit, use the vent shaft or hack the security computer if you have neural interface biomod installed. You can also toss the explosive crate into the laser beams.
Use the medbot in the hall (and return to it as necessary). Next lab has two order seekers, a turret, and a camera. Kill them or avoid them. There's a computer to hack on the left side of the room that can disable the camera and release an ally spiderbot. If you use the vent to exit the first lab, you can get some credits and an energy cell from a cabinet (use the multitool to unlock it) and follow another vent (eliminate the spiderbot) to reach girders overlooking the lab with the order seekers. Search the lab for a multitool and proceed to the exit.
At the exit you speak with Lin-May Chen who provides a new objective.
