Iguazu Falls, Brazil

Eavesdrop on Jake's phone conversation with the new gadget, spy braces. 


Use the control keys to move the charater to where Jake is talking. In order to hear what he is saying on the phone, the player's character need to stand in the green zone. If the player's character stands in the red zone, he will spot them! The player must hear 75% of the conversation to advance.


Jake plans to take Amy to Norway, so he isn't the Vesper Shield as V-2 was banned from Norway. Ian finds it heartwarming and wonders what Evan will say about that.

INVESTIGATION - LaCher Siffright[]

Iguazu Falls, Brazil

Talk to Isabel Kabra, an acquaintance of LaCher Siffright's, to try to get any information Ian also tells the player not to mention him to Isabel because of what happened the last time they were together. MINIGAME:

Choose the correct speech bubbles and try not raise suspicion. The player must reach 75% trust to get the information needed. 



LaCher Siffright loves animals; she owns two dogs and four cats. Therefore, she cannot be Vesper Two.

INVESTIGATION - Arthur Josiah Trent[]

Poenari Citadel, Romania

Another Vesper stronghold is discovered: Poenari Citadel in Romania. It's really dangerous to break in. Instead, the player uses another new gadget, the Madrigal glider.


Timing is key! Hold down S key to dive toward the fog. Release the S key to release the glider. Press SPACE to use a booster for a quick push or relaunching the glider. The player must get to the Citadel before the glider runs out of power. 

After the glider gets in, the player receives 4 surveillance photos. See them all. The important picture is the last one


Arthur has traveled to Cambodia, so he's not the Vesper Shield as the Shield was banned from Norway.

INVESTIGATION - Dave Speminer[]

New York City, USA

Recently, the Vespers hacked into New York Power Glide to send messages in Morse Code. Head to the viewing point to see the city, and those blinking green light.


Watch the light in morse code carefully and compare it to the cipher below. When the player identifies the first letter, type it in the box. If correct the next letter will begin flashing.





V2 uses boats for transport, and since Dave is afraid of water, he can't be the Vesper Shield.

NOTE: New info added to V-2 characteristics - Travels by boat Only two left Beatrice and Isabel.

INVESTIGATION - Beatrice Cahill[]

Boston, Massechusetts, USA

Aunt Beatrice could be V2, so we broke into her apartment. We need to open her box.


Place the pieces in the correct slots to unlock the box. Work quickly, as the box has a defense machanism that causes the pieces to pop out every few seconds


The box contains Beatrice's report from flight school.


Beatrice had failed flight school, therefore she cannot fly a plane and can't be the Shield.


Vesper Two[]

After eliminating five suspects, it is confirmed that Vesper Two is Ian's mother, Isabel Kabra. This upsets Ian very much knowing he has to confront his mother eventually to free the hostages.
