Here is a sample of my environment and character models.
These office models are currently used in my competitive-stealth-tactical shooter (tentatively titled, Unreal mod) Intruder. It is important to note that all of these models were designed with gameplay in mind. For example, the books seen in the second screenshot are not completely solid, but have been modeled so they can open up. I wanted them to fly open as gunfire ripped through them and other office materials. Multiple different door types have been created not only for visual variation, but to allow tactical choices as far as vantage points and line of sight i.e. doors with glass can be seen and shot through. The tables and cabinets are just so low that a crouching player can use them as cover while still firing shots, and just so high that a player who is prone would be hidden from view.
The submachine gun style weapon, known as the Kriss Super, was speed modeled in a one day period. Weapon modeling has become a specialty of mine. The other character and weapon models are also currently used in Intruder.
