Temple - With its wide corridors, large open room, and relatively simple floor plan, the Temple is a great level for beginning agents. The central room is so large that it can be difficult to see someone at the other end without a rifle scope. A gaping hole in the middle of this room's floor allows you to snipe down on targets on the lower level. Rating 2/10

Complex - As its name suggests, the Complex is one of the most intricate Multi-player levels. The sprawling layout features many twists and turns, and the multiple floors makes it difficult to know exactly where your opponents are, even when using the radar. There are also many sniper positions scattered throughout the maze, but few of these offer complete security for the shooter. You can also hide in the ventilation ducts and ambush opponents from there. Rating 5/10

Caves - Poor lighting conditions make the subterranean caverns a confusing and deadly place for a firefight. There are plenty of sniper lookouts, switchback passages, and darkened ambush points. Because it's easy to get turned around, the caves are an amusing location in which to have fun with the different explosive mines. Rating 4/10

Library - The massive Library is one of the largest Multi-player arenas, with a full basement and upper floor. The main floor features wide open rooms with multiple levels, and several secret passages. Below, the library basement offers a dimly lit and confusing floor plan to befuddle agents who start there. When hunting in the Library, you can shoot through the grates in the floor down into the basement, or vice versa. Rating 9/10

Basement - The Basement is the lower floor of the Library. Two large rooms with many pillars create a confusing arena for a pitched gun battle. The dark corridors of the basement make for possible ambushes by a stealthy player. Rating 7/10

Stack - If you choose the Stacks, you'll compete in just the upper level of the Library. Although the Basement is locked, there is still plenty of action potential in the upper floor. Use the upper level perches and secret passages to snipe at or ambush your opponents. Rating 9/10

Facility - One of the smaller Multi-player arenas, the Facility makes for a fast and furious battle. Because of its size, you can count on reappearing near someone after you die. There are not a lot of places to hide here, although the restroom on the upper floor is a favourite spot to stage an ambush, especially because it is there that you can usually find the special weapon for the match. Rating 9/10

Bunker - Large and well-lit, the Bunker is a good arena for beginning agents to practice their lethal skills. An agent who knows the floor plan can really lead pursuers on a wild goose chase through the maze of this level. Look for the arena's special weapon in one of the side rooms of the main Control Room. Rating 7/10

Archives - Part of the GRU Military Archives have been blocked off and converted into a Multi-player training ground. The corridors of the archives are littered with crates which will explode when you shoot them. Although you can find weapons in some of the offices, they can also be death traps if someone pins you down inside. A secret passage will let you escape from the dead end by the offices on the upper level. Rating 10/10

Caverns - The Subterranean Caverns in Cuba make for a sprawling combat training zone. This level is spread out between several different locations, which are connected by a long series of walkways. You'll have to do a lot of running around in this level to get from one location to another. Rating 7/10

Egyptian - This secret level is based on the Egyptian temple of Baron Samedi. Ubiquitous pillars will obscure line of sight, making for savage, close-in firefights. This area is reserved for two-player matches. Rating 3/10
