"Backbone" pits Tarn and Nogari forces against each other high in the clouds, atop a high altitude Dropship. With open platforms and a perilous drop threatening to punish any misstep, enemy fire is not the only thing that you need to watch out for.

"Backbone" is playable in Deathmatch, Team Deathmatch and Capture The Flag modes.

"Epsilon" features a massive, concentrated pool of Ambrosia in the lower level, which also serves as a hub providing easy access to all main areas of the map. Scattered around this incubation facility are a number of containment devices full of toxic gas. Damaging them will cause their force fields, allowing this gas to irradiate the immediate area temporarily until the fields come back online.

The night before Echo Squad's assault on Nogari Island, they carried out an operation in the Bering Sea in which they finally discovered the whereabouts of Dr. Eugene Reisbeck. "Intrustion" is set in the underwater Nogari research facility that Echo attacked to retrieve this information. The central Hangar's inviting waters spell certain death due to high temperatures from nearby natural thermal vents. Cramped maintenance tunnels offer a wide variety of flanking paths between every part of the facility, allowing you to escape or intercept enemies quickly.

"Intrustion" is playable in Deathmatch, Team Deathmatch and Capture The Flag modes.

Scattered around Nogari Island are various temples and shrines built by the Corporation's "Divine Leader". Embedded in several monuments are fragments of pure Ambrosia which constantly emanate energy towards other nearby fragments. "Nexus" is dominated by a central temple that overlooks the grassland and rock formations around it, serving as a hub and offering fast access to all strategic areas. Rocks, ravines and caves offer a wide variety of environments that are perfect for sneaky infiltrations or quick getaways.

"Nexus" is playable in Deathmatch, Team Deathmatch and Capture The Flag modes.

Close quarters combat is the order of the day in "Omega", where Tarn and Nogari forces fight a fierce war of attrition amongst the corpses of the Scourge outbreak's first casualties. Beware of the laser 'decontamination' security system, for Nogari's notion of 'cleansing' is rather... permanent.

"Omega" is playable in Deathmatch and Team Deathmatch modes.

High-speed train transit stations are located all over the underbelly of Nogari Island, forming an intricate network that connects hundreds of different facilities. In "Station", two platforms are divided by an energy rail conduit through which a deadly train frequently passes. The central cross-bridge on the upper level connects the two main balconies and provides easy access to all levels below.

"Station" is playable in Deathmatch, Team Deathmatch and Capture The Flag modes.
