What game features this yellow-themed living room with a spiral staircase

Decided to turn my comment into an answer.

The first picture you posted was a picture of Vector from Resident Evil: Operation Raccoon City. You can find a description and picture of him here. Additionally, if you search for "Resident Evil Vector" in Google images, you'll see a plethora of images of him.

The second picture is also from this game, although I'm having trouble verifying this with a reference or image. This is the best I could find (which also has Vector).

Edit:

Here's the info on Christine Yamata, the person in the second picture, also from Operation Raccoon City.

This game is called Bridge Constructor.
