NOTES ON THE REMASTER: At this point I can't guarantee 100% accuracy for this guide. Updates are in progress but will take time. Levels that have been worked on will say "Remaster," rather than "Classic," in the title. In the meantime, I have attempted to provide a running count of all kills and pickups, including totals for health packs, chocolates, sellable items, and cash, as well as notebook entries, which are needed for some achievements/trophies. If I've missed any, I do apologize. Please let me know if you discover anything not mentioned here. Also, in case it's not obvious, these guides are based on classic tank controls, and I have not yet included strats for all achievements/trophies.
LEVEL 24: MAXIMUM CONTAINMENT AREA (Remaster)

LEVEL MAP by VGCartography (used with permission)*
Angel of Darkness Remastered Video Walkthrough by Eldincy
Items: 10, including 1 health item, 2 chocolates, Farsee Code, and 2 Security Passes
Kills: 8
Upgrades: none
Notebook Entries: none
Cutscene: A quick flyby of the area.
SANITARIUM CORRIDORS: Follow the hall to a barred door, open it and go through. You'll need a code to use the computer in the glassed-in office on the left. Let's go find it. But first, head down the hall to the right. Quick-save and jump in the pool. Kurtis will die instantly, but if you also allowed Lara to get mauled by the first dog in the first level and shot by Bouchard in his hideout, you'll unlock the "Darwin Awards" achievement/trophy here. (screenshots)
To get across the pool, face the right wall, sidestep as far to the left (toward the water) as you can. Then jump up to grab the wires running along the wall. Traverse across and drop down on the other side. Pick up a Boran clip (1) and return across the pool the same way. Again, make sure to sidestep toward the pool as much as possible before grabbing the wires, otherwise Kurtis won't have enough strength to make it to the other side. (screenshots)
Return to the glassed-in office and turn right. Follow the hall through two doors, one barred, one set of double doors with windows. Beyond them is another dingy ward with closed and open cells. Turn right, approach the second door on the left side of the hall, and try to open it. (screenshots)
Cutscene: Kurtis uses his farsee ability to scope out the next bit of code, printed on an inmate's back: 17068.
This FARSEE CODE: 17068 (2) is noted in your Inventory under Items. Return to the glassed-in office, go inside, and enter the code on the computer console. This opens various doors in the ward where you saw the code. Exit the office and turn left. Return through the barred door and double doors to the dingy ward. (screenshots)
NOTE: Again, from here onward, try to use the Chirugai and save your Boran X ammo for the boss fight in Kurtis's final level. Review the controls for Kurtis at the start of the SANITARIUM if you need a refresher.
The next two kills are optional. If you'd rather avoid this encounter, turn right here and skip to the next paragraph. If you want all kills, at the four-way intersection just beyond the double doors, proceed straight ahead, then around the corner to the right. This hallway dead-ends at a large, metal door. Enter the open cell on the left to spawn 2 clawed mutant inmates (1-2). Fighting in the small cell with the fixed camera angle can be difficult, but you can also use the doorway as a bottleneck. Draw the Chirugai and move forward just far enough to see the the doorway. When the mutants approach, press Duck to activate the psychic shield. Then throw (Action) or slash with the blade (Jump) at close range to kill them quickly. When the coast is clear, return to the four-way intersection. This time, turn left toward the door where you got the FARSEE CODE earlier. (screenshots)
Open the first door on the left. Inside is a padded cell containing the inmate with the code on his uniform. A window gives you a glimpse of some goodies in the next room, and Kurtis remarks, "What the hell have they been up to in here?" Continue along the corridor to the second room on the left, where you obtained the FARSEE CODE. Go inside but get ready for another clawed inmate (3), who spawns out in the hallway to the left. You can either run back into the hall and head to the right to get some maneuvering room. Then throw the the Chirugai a few times. Or, wait inside the office, and when the mutant approaches, press Duck to use the psychic shield. Then kill the inmate by throwing or slashing with the Chirugai. Grab the Boran ammo (3) and a SANITARIUM LOW ACCESS PASS (4) sitting near the dead guard, plus a chocolate bar (5) on the desk. (This is Kurtis's 4th chocolate bar and 19/20 for "Chocollection.") (screenshots)
Exit the room and go to the left. Swipe the pass card in the card reader to raise two metal doors: one directly ahead, one on the left just beyond the first door. Step forward into another 4-way intersection. On the left is the hallway with the open cell where you encountered the 2 clawed mutants (1-2) earlier. Again, if you don't want to fight them, just avoid that area. Ahead, just to the right of the double doors with the rectangular glass windows, is another open cell. Inside, you'll find a bag with some Boran ammunition (6) sitting on a cot. Grab the ammo. Then exit the cell and follow the hall to the left, down the ramp, and through the double doors to a new area. (screenshots)
SQUARE HALLWAY WITH LABORATORY & SIDE PASSAGES: This hallway contains several enemies: 2 clawed mutants (4-5) that may approach from either side, and a soldier (6) in the duct at the end of the hall directly ahead. Don't approach the soldier, or you'll waste valuable health and ammo. Instead, head to the right, past the laboratory door. The first mutant should approach as you near the next corner. Again, draw the Chirugai and press Duck to activate the psychic shield as soon as you spot the mutant. Throw the Chirugai (Action) as it approaches. Then, if necessary, switch to slashing attacks (Jump) at close range to finish it. When it falls, turn around and return past the lab. The next mutant should then approach around the corner to the right. Deal with it the same way. Now backtrack to the lab and open the door. (screenshots)
Cutscene: The Proto-Nephilim runs out past Kurtis and deals with the armed soldier in the duct.
NOTE: The game counts the soldier as an official kill, even though the Proto does the deed.
Unless you want all kills, do not enter the lab. If you do, another clawed mutant (7) appears behind you. You may be able to subdue it with melee attacks, but you're probably better off running inside, turning around, and using the Chirugai, as you did with the other mutants. (screenshots)
There are a few closed doors and side passages leading off the square hallway surrounding the lab. One door, at the far end of the hall, diagonally opposite from where you first came in, has a card reader. You'll need another keycard to open it. (screenshots)
For now, head for the duct where the Proto killed the soldier. Crouch and go through. At the end of the duct is a curved staircase. Here Kurtis muses, "I musta been real bad to deserve all this." The way up is blocked by debris, so head for the bottom of the stairs. Then follow the corridor to a barred metal door. Open it and continue to the Proto containment area, which you saw in an earlier cutscene. (screenshots)
PROTO-NEPHILIM CONTAINMENT AREA AND MORE DUCTS: Follow the curved walkway around to the right. Climb the ladder. Then continue along the upper walkway toward the brightly lit window. You can't get in here, so approach the containment chamber at the center of the room. Here Kurtis will say one of several possible scripted lines. (See the note below.) Climb on the roof of the chamber and then jump and grab the edge of the broken walkway on the right. Pull up and follow the walkway around to the left. Jump the gap and grab the opposite edge, pull up, then climb into the square duct ahead on the right. Follow it through several twists and turns. (There's no danger, and although there are a few dead-end side passages, you can't really get lost.) At the end of the ducts, somersault out into a cylindrical shaft with a broken fan below. Climb the ladder to a room with 2 dead guards. Pick up a chocolate bar (7) and the SANITARIUM MEDIUM ACCESS PASS (8). (screenshots)
NOTES: Interestingly, as Kurtis approaches the containment chamber, he has several possible lines of dialogue: "So this is where they kept the Proto—till they lost power—good work, Lara," or, "They managed to keep the Proto in here—till they lost power," or possibly, "Clever girl, Lara. You've let the genie out." Which one you hear appears to be random. Also, the chocolate bar in this room is the last one in the game. If you found all 20 and didn't eat any of them, the "Chocollection" achievement/trophy should pop here. Now, you can finally enjoy some of that delicious sewer candy!
Press the button to open the door. Go through into the SQUARE HALLWAY where you were before. Turn left, then left again. Use the MEDIUM ACCESS PASS in the card reader to open the nearby door. Check that you have everything you need in this area, then go through to confront the Proto-Nephilim. (screenshots)
Cutscene: The Proto has had its fill of soldiers and has now developed a taste for Kurtis. Not wanting to become a monster's dessert, Kurt uses his telekinetic power to bring down a heavy metal door, trapping the Proto on the other side. But the mutant won't give up so easily. It finds a way in through the ducts.
KILLING THE PROTO-NEPHILIM: There are two possible achievements/trophies here. "Great Flood" is unmissable. You just need to defeat the Proto any way you can. "You're Just a Monkey" requires you to kill the beast without using the Boran X or healing. I found that using the Chirugai is actually easier than the gun. But if you're playing the original game, where the Chirugai is not available, check out the Boran strats in the classic guide.
You'll need to subdue the Proto-Nephilim (8) four times in order to actually kill it. So, as soon as you regain control after the cutscene, equip the Chirugai and activate the psychic shield (Duck). Kurtis may take a little damage while you're doing this, but once the shield is active, it helps protect him from the Proto's attacks. Now quickly throw the Chirugai (Action) or slash with the blade at close range (Jump). When the shield dissipates (Kurtis stops glowing), re-activate it by pressing Duck again, and continue fighting. The goal is to do as much damage as possible, as quickly as possible. So don't be afraid to move in close, as long as Kurtis is shielded. When its health bar is reduced by about half, Kurtis will no longer target the Proto. It will then scamper off into the air ducts, giving you a few moments to regroup. (screenshots)
During the lull, when the Proto climbs up to the ceiling, you can pick up the large health pack (9) in the near left corner of the room and/or unlimited Boran ammo (10) in the far left corner. (This pickup respawns but only if you run out of ammo. It gives you 2 more Boran clips each time you pick it up.) You will be able to get these pickups after the fight, so leave them for now unless you're desperate. (screenshots)
Watch the ducts on the far wall, and when the Proto emerges, re-activate the psychic shield and continue throwing the Chirugai. After two or three more hits, the Proto will retreat into the ducts again. Repeat the process twice more: Activate the shield as the Proto climbs down to the floor, then throw the Chirugai to chip away at its health. The fourth round of attacks should reduce its health to zero. When Kurtis says, "Time to die, Monkey," it's over. (screenshots)
Cutscene: Kurtis stabs the Proto-Nephilim with his Periapt Shard. The beast gets a brief second wind then falls dead. The "Great Flood" achievement/trophy unlocks here.
After the cutscene, Kurtis deadpans, "That's my demon quota for today. Time to get the power on again." If you managed to defeat the Proto without healing or using the Boran X, the "You're Just a Monkey" achievement/trophy unlocks here.
Pick up the large health pack (9) and Boran ammo (10) if you didn't get them during the fight. Approach the machine with all the hoses and dials. Pull the switch to turn on the power. (screenshots)
Cutscene: Kurtis returns to the airlock where Lara is trapped. She ambushes him and, while holding him at gunpoint, fends off another sanitarium mutant. Then Lara frisks Kurtis and disarms him.
Once they've established some mutual trust, they discuss what to do next. Kurtis reiterates Eckhardt's plan to revive the Nephilim and fills in a few gaps in Lara's knowledge. We learn that Eckhardt, the "original Black Alchemist," plans to use chemically transmuted elements from his victims' bodies to help achieve his goal, but he also needs the final Obscura Painting. Kurtis explains that Eckhardt can be killed if he is stabbed with all three Periapt Shards. He and Lara have two, but the third is still in Eckhardt's possession. Since the way to the painting, through the Vault of Trophies, lies underwater, and Kurtis apparently can't swim, they agree that he'll go after Eckhardt's shard and Lara will find the last painting and destroy it.
Second cutscene: Eckhardt and Karel are discussing the progress of the Evil Plan™. Like all respectable villains, Eckhardt has decided to let the good guys do his dirty work. He'll allow Lara to find the last painting for him. Then his preparations will be complete.
†UPDATE HISTORY: Updates made prior to the Tomb Raider IV-V-VI Remastered release, including credit for tips sent in by other players, are tracked in the archived classic guide.
7/13/25 - Remastered guide posted.
7/24/25 - Added the note about saving Boran X ammo for the boss fight. This was implied in earlier versions, but after some experimentation, I'll say it plainly.
*NOTE ON LEVEL MAPS: VGCartography's Angel of Darkness maps follow a slightly different level-numbering convention than I do. You'll notice most of the Parisian Ghetto-adjacent areas on the same large map. Later, the elemental levels off the Hall of Seasons are included on the same map as the hub level. Visit VGCartography on DeviantArt and follow on Twitter/X and YouTube for more fantastic game maps.
