By now, most marathon gamers have finished up their first run through Metal Gear Solid 4: Guns of the Patriots. But don't worry if you're still lagging behind - take your time. There's a lot to experience in MGS4, so savor it. For those that are looking for more to do in Hideo Kojima's opus, the first place to start is collecting all of the alternate FaceCamos and costumes hidden throughout the game. We'll break them down for you, and even tell you how to get them all. Be warned: there are spoilers in the list below, so if you haven't finished the game, now is a good time to bail out, unless you really want to hunt for the secrets on your first run.

Command Vests

Command Vests don't do much but make sure Snake's outfit matches, so managing them really isn't something you should worry about. The game begins with five different colors available (khaki, olive drab, black, grey, navy blue), with another five to unlock by beating the game once (green, blue, red, orange, tan).

FaceCamo

The FaceCamo is an add-on to your OctoCamo that you receive at the end of Act 2. You'll get a number of FaceCamos strictly by progressing through the game, but there are a number of secret masks to unlock as well. Here's how to get them:

FaceCamo

Defeat Laughing Octopus.

Young Snake

Obtained at the beginning of Act 3.

Young Snake with Bandana

Costumes really only serve to make Snake look cool. Sure there's one act when it's encouraged to wear a costume, but it's not even remotely necessary. Here's what you can get:

Secret Items

They're not technically part of Snake's outfit, but these items are mainstays for the series and requisite challenges for Metal Gear fans.
