Capsule toy company System Service is following up its popular but now hard to find Metal Gear Solid 4 Ration Sound Keychains with another series, thsi time allowing you to play sound effects and phrases from the PS3 game's central figures -- Snake, Otacon, Raiden, and Liquid Ocelot. Just push on a keychain's button, and you'll hear a Japanese message like "Mataseta na" ("Kept you waiting, huh?").

These toys are typically sold individually and randomly through gashapon dispensers in Japan, but you can still buy a set in the States. Online import shop NCSX is accepting preorders ($30.90!) for the Series 2 set, and plans to ship the keychains some time in mid-to-late December.
