Here's a set of Section 8 screenshots and a trailer from the just released Seek and Destroy Map Pack, to purchase, select 'Downloadable Content' from the main menu which should set you back 560 ms points on the Xbox, not sure if it works on the PC.

Players will be able to fight for control of a geothermal energy plant on the salt flats of New Madrid in "Devil’s Backbone" and battle in the narrow confines of a hazardous valley on the planet Titan in "Hornet’s Nest". "AzureBasin" is set high atop a mountain plateau where a massive hydroelectric dam sits astride the map, with combat ranging from both inside and outside of the facility.
