Investigating Bandel’s theater and greenroom

Head right and crawl through a vent to access restricted areas. This introduces environmental navigation early on.

Step 4

Climb the ladder and retrieve the key from the water tank. Then use nearby switches to unlock stage access.

Step 5

Enter Bandel’s greenroom and collect key clues. You’ll find a book revealing an address and a poster photo, both essential for progressing.

Step 6

Search thoroughly for optional collectibles like newspapers. These are easy to miss but valuable for completion.

Finding key to the greenroom, collect clues and leave theater

Step 7

Exit the theater and prepare for your first real combat encounter. Enemies will ambush you immediately.

Step 8

Find the key in a sealed container inside the greenroom area, opposite to the police officer.

Step 9

Use the key to open the greenroom. Find a drawer to retrieve the clues.

Step 10

Save your progress at a typewriter before moving on. Frequent saving reduces frustration from unexpected fights.

Exploring the assistant’s apartment

Step 13

Look for hidden rooms and collectibles, including a baseball card. These are often tucked behind breakable walls.

Solving the loft key puzzle and unlocking rewards

Step 15

Shoot a hidden explosive barrel behind a cracked wall to open a new path.

Step 16

Clearing enemies and gathering resources

Step 18

Use environmental traps like dropping an anvil on enemies. This saves ammo and speeds up encounters.

Handle outside enemies using explosive barrels for quick clears.

Step 20

Navigating the subway section

Step 21

Step 22

Crawl under pipes and interact with switches to unlock pathways.

Step 23

Break walls and windows to uncover hidden routes and loot.

Step 24

Prepare for combat when enemies arrive via the subway train. This is one of the mission’s more chaotic fights.

Step 25

Optional interactions include speaking with a janitor and collecting another schematic.

Meeting Betty and uncovering the next lead

Step 26

Reach the top-floor apartment and speak to Betty Deux-Fiddle. This scene provides major narrative clues.

Step 28

Search the kitchen for an additional newspaper collectible.

Returning to town and preparing for the next phase

Return to town and explore optional areas like the bar and shop. You can engage in mini-games or stock up on supplies.

Get to the car.

Step 32
