You can find an interview with 3DCreative magazine regarding environment art in Crysis 2 here
Breakability / Bendability: During the production of Crysis 2 I was responsible to integrate breakability and bendability into all of our meshes. I managed and outsourced the modeling work to a
team of up to five people in the Kiev studio and also improved and bugfixed the existing tech. All of the technical setup regarding breakability and bendability was done by me.
Carpark: I created the entire carpark. All models and textures except the smaller props (concrete barriers, red plastic barriers, wooden barriers, furniture, metal fences, cardboard boxes, cones, cars, vegetation, modular rubble pieces and background buildings)are done by me. The carpark was widely used in Crysis 2 and turned into a modular set that has been reused in several other maps and in MP.
City Hall: I created the entire City Hall building including Front and backside. The backside was cut due to gameplay changes. All other objects in the screenshots that are not part of the City Hall building are created by other artist.
Castle Clinton: I created the entire Castle Clinton. The generic props on the inside and the background objects are created by other artists.
Municipal building: I created the Municipal building. Some parts had to be reused from other assets due to time constraints (lower level modular windows, pillars, tiling rubble texture)
Flatiron building: I created the Flatiron building. Everything in the screenshots that is not part of the building is created by other artists.
Brick building: I modeled the brick building for the Warehouse level. Due to time constraints this had to be done in four days so all elements of this building are created by other artist (textures, detail props, etc). I was only responsible for the modeling.
Military barriers and concrete barriers: I created all military and concrete barriers. All of the background elements are done by other artists.
