Level Design: Shooter

For my level design, I'm thinking maybe some sort of futuristic mall with a setup like the game Dead Rising.

The architecture would be very modern, sleek and angular. Since this is an interior area, there wouldn't be any type of vegetation except for the occasional fake plant. I want to have middle key lighting with lighting to help direct the player throughout the gameplay. I want the mall to be abandoned, so various clutter pieces will be scattered throughout the level.
