Mission walkthrough

  1. Follow Millie from the casino

    Keep her car in sight while maintaining distance. Watch the suspicion meter and ease back if it rises; getting too far behind also loses the target.

  2. Enter the shop and take the outfit

    Follow her inside, reach the indicated area and collect the required outfit. Leave and resume the tail without driving directly into the rear of her car.

  3. Wait near her home

    Park outside the marked house. Intercept the expected visitor before he reaches the door, then approach the doorbell in the required outfit to complete the scene.

  4. Obtain the keycard afterward

    Continue the relationship until the progress requirement is met, around 35%, and follow Millie’s call or instruction to collect the card from her house. Confirm the card pickup before expecting the casino heist to unlock.

Key point

The most common progression mistake is treating the mission-passed message as the keycard reward. The card is a later pickup and remains necessary for Breaking the Bank at Caligula’s.

This branch is optional for reaching the story ending, but it is required for 100% game completion.
