The A New Home chapter in 007 First Light hides four collectibles as Bond settles into his Bayswater base and runs through advanced training. You get two Intel files inside the apartment, then two playing Cards out in the Malta training grounds.
Nothing here is missable. Every collectible can be picked up later through Chapter Select, and each one saves the instant you grab it, so you can quit out immediately after collecting in cleanup mode. The Q-Watch, unlocked earlier in Chapter 4, highlights nearby collectibles in yellow when you hold L1.
Intel: Family Photo (Lennox Monroe) — Home checkpoint
This is the first collectible of the chapter, and it sits in plain sight as you arrive.
Step 1: As soon as you enter your new home, walk straight ahead into the living room where Monroe is waiting.
Step 2: Look at the chest of drawers against the right wall, near the door, topped with two mirrors. The Family Photo of Lennox Monroe is sitting on it. Inspect and flip the photo to log it as Intel.

Intel: Dress Box (Cressida Bright) — Home checkpoint
The second Intel file comes during the same apartment sequence, tied to the objective to see what Cressida wants.
Step 1: Continue down the main hallway and head into Cressida's bedroom when she calls you in. It's the second door on the right at the end of the hall.
Step 2: Interact with the gift box on her bed to collect the Dress Box Intel.

Card: Under of Acorns — Advanced Training checkpoint
This card only becomes reachable after you open the first gate, so you can't grab it the moment you arrive.
Step 1: When you return to Malta for advanced training, move forward to the first gate and hack it to enter the training area.
Step 2: Turn around and backtrack to the starting area where Greenway explained the rules.
Step 3: Climb the stairs to the platform. The Under of Acorns card is on the ledge straight ahead from the top of the stairs, against the brick wall.

Card: 7 of Roses — Search the Compound checkpoint
The final collectible is in the nighttime flag sequence, during the objective to steal the flag. You can grab it on a stealth run or a loud one.
Step 1: Drop into the courtyard where two soldiers are chatting after splitting from Monroe, then head down toward the pier area.
Step 2: Find the large double door by the stairs. Either kick it in, which alerts nearby enemies, or take down the helmeted guard on the stairs first to grab a key and open it quietly.
Step 3: Go through the doorway into the room with three guards. Bluff your way past them and take the 7 of Roses card from the pallets on the right.

How to confirm you collected everything in A New Home
Each collectible flashes "New Collectible" in gold text on the right side of the screen when you pick it up. Items that count toward completion show a small gray bookmark icon next to their name when you look at them, which helps separate them from the many readable photos, newspapers, and text files that don't count.
There's no per-chapter collectible tracker in 007 First Light, only a count by type when you press the Touchpad. To verify A New Home specifically, the chapter contributes two Intel (Family Photo and Dress Box) and two Cards (Under of Acorns and 7 of Roses). If you're missing any, jump straight to the Home, Advanced Training, or Search the Compound checkpoint through Chapter Select and follow the locations above.
