Metal Gear Solid: Peace Walker/Downloadable Content

In Metal Gear Solid: Peace Walker, there are downloadable content used via the PlayStation Network. Some of the DLC content included special uniforms, special Walkman songs, AI voices, special VOCALOID song programs and, in the Japanese version, special magazine weapons. Other than password unlocks, only 15 DLC packages have currently been released in Japan, 12 of which were also released in America. It should be noted though that the HD versions of Peace Walker for the PlayStation 3, and Xbox 360 include a large portion of the DLC.

Uniforms
Special DLC uniforms are available via DLC. The uniforms usually have a varying amount of benefits for camouflage, but generally are not that good. The uniforms, with the exception of Comrade and Guns&Jungle, also come with a "naked" function, and with the exception of Yellow, Khaki, Green, Water, and Treebark (which rank "C" on Sand, Sand/Rock, Jungle, Swamp, and Tree environments, respectively), none of the naked variants have a single decent camouflage setting. In addition, with the exception of the 12th DLC uniform, the naked uniforms are of the same set as the regular uniforms.

Black
The first DLC-unlockable uniform. It is colored black and boasts decent camouflage in Jungle, Concrete, Swamp, Tree, Dirt, and Ruins, but is below average in regards to Sand and Rock.

Pink
Second DLC-unlockable uniform. It is colored pink and passing, but not decent camouflage, making it ill-advised to use in a sneaking mission.

Navy Blue
Third DLC-unlockable uniform. It is colored Navy Blue and possesses decent camouflage in Jungle, Swamp, and Ruins environments, but passing and yet not stellar camouflage in every other environment.

White
Fourth DLC-unlockable uniform. It is colored white and possesses decent camouflage in Sand, Concrete, Tree, Dirt, and Rock environments, and passing yet not stellar camouflage in Jungle, Swamp, and Ruin environments.

Red
Fifth DLC-unlockable uniform. It is colored Red and, similar to the pink camouflage, has passing yet indecent camouflage in every environment.

Yellow
Sixth DLC-unlockable uniform. It is colored yellow and possesses outstanding camouflage in Sand environments, decent camouflage in Tree, Dirt, and Rock environments, and not too decent camouflage in Jungle, Concrete, and Swamp environments. The Naked variation of the uniform possesses bad camouflage in every environment except for Sand environments, which have relatively decent camouflage.

Khaki
The seventh DLC-unlocked uniform. It is colored Khaki and possesses very decent camouflage in Sand and Rock environments, decent camouflage in Concrete, Tree, and Dirt environments, and passable camouflage in Jungle, Swamp, and Ruins environments. With the exception of Sand and Rock environments, the naked variation of the Khaki uniform has bad camouflage in all environments.

Green
The eighth DLC-unlockable uniform. It is colored Green and possesses good camouflage in Jungle environments, decent camouflage in Swamp and Ruins environments, and passable camouflage in Sand, Concrete, Tree, Dirt, and Rock environments. The naked variant of this uniform also has relatively decent camouflage in Jungle environments.

Water
The ninth DLC-unlockable DLC uniform. It is patterned after water, and as such has the best camouflage properties in areas with water, and has overall decent properties in other environments. With the exception of Swamp environments, the naked variation provides bad camouflage with all environments.

Treebark
The tenth DLC unlockable uniform. It is patterned after Tree barks, and has good camouflage in Jungle and Tree environments, and decent camouflage in Sand, Concrete, Swamp, Dirt, Rock, and Ruins environments. With the exception of Tree environments, the naked variation has bad camouflage abilities in all environments.

DPM
The eleventh DLC-unlocked uniform. The primary camouflage pattern utilized by the British forces as well as former colonies of Britain, it has brown, green, black, and beige colored patterns, and has very good camouflage in Jungle and Dirt environments, and decent camouflage in other environments.

Comrade/Guns & Jungle
The twelfth DLC-unlocked uniform(s). The Comrade is patterned with black, gray, white, and yellow camouflage colors patterned after the Militaires Sans Frontieres logo and is decent in Concrete and Rock environments, and passable for Sand, Jungle, Swamp, Tree, Dirt, and Runs areas. Guns and Jungle has green and brown prints with the latter color being in the shape of guns, and has very good camouflage in Jungle environments, decent camouflage in Swamp, Tree, and Ruins environments, and passable camouflage in Sand, Concrete, Dirt, and Rock environments.

Promotional passwords
In addition to the above methods of unlocking special items, DLC content for Peace Walker can also be unlocked via password when entering the extras menu. They include a HORI shirt, a Walkman shirt, a FOX shirt, Uniqlo shirts, a Doritos shirt, a Pepsi NEX shirt, a Mountain Dew shirt, an AXE shirt, and a Lawson shirt. With the exception of the first four items, all of the items are available only in the Japanese versions of Peace Walker, and can be gained from HORI products, a limited edition camouflaged Walkman, a limited edition bundle of Peace Walker, the Uniqlo t-shirt line (with one for each of the 14 variants of the shirts counting different color variants, and a UT logo), limited edition Mountain Dew cans, specially marked AXE products, and Lawson stores, respectively. In addition, the Play Arts Kai line of Peace Walker toys are stated to have passwords, although they mostly unlock new soldiers and nothing else. The sole exception to this rule was the Big Boss Sneaking Suit figure's password, which allowed for a FOX t-shirt to be unlocked.
