Metal Gear Solid 4: Guns of the Patriots/Downloadable Content

In Metal Gear Solid 4: Guns of the Patriots, there are downloadable content used via the PlayStation Network. Some of the DLC content included special OctoCamo patterns, special iPod songs, integral podcast sessions, and at least one password.

OctoCamo patterns
Special DLC OctoCamo patterns are available via DLC. The patterns usually have a varying amount of benefits for camouflage, but generally are not that good. However, they also include special benefits other than decent camo.
