Play Arts 改 -KAI- [プレイアーツ改, Purei Ashi KAI, lit. Play Arts "Revolution"] is Square-Enix's line of improved (and upsized) Play Arts action figures that début in November 2009. It is also under Square-Enix's "Black Label Collectors" line-up. Unlike its predecessor line-up "Play Arts," Play Arts KAI includes franchises outside Square-Enix and Eidos such as Konami, Platinum Games, Capcom and even Shonen Jump characters, one of the series happens to be the Metal Gear series. Play Arts KAI figures are sculpted by OOParts.
Play Arts Kai's first involvement with the series was the announcement of the Metal Gear Solid: Peace Walker figure of Snake in his Sneaking Suit. The figure included 2 Mk22 Mod-0 pistols, 1 Hush Puppy suppressor, a Ballistic Shield and a pair of changeable hands. The figure also included a code to download a special recruited solider onto the PSP version of Metal Gear Solid: Peace Walker. The Sneaking Suit ver. was released in June, 2010. A Vol.2 set of figures was released this time being 3 of the AI weapons, PUPA, CHRYSALIS and BASILISK. Each one also came with a PSP code. They were released on September, 2010. Vol.3 featured Snake again, this time in his Jungle Fatigues attire. The figure came with a Mk22 Mod-0, a M16A1, a Stun Rod and a changeable hand. The set also involved the COCOON and ZEKE AI weapons as well, all 3 of them came with PSP codes. They were released on November, 2010. The final set Vol.4 contained Snake in his Battle Dress attire and Kazuhira Miller. Snake came with a Mk22 Mod-0, a M60, a RPG-7, a changeable head and a changeable hand. Miller came with a Mk22 Mod-0, a M16A1, 2 pairs of sunglasses, a changeable head and a pair of changeable hands. No PSP codes were included in this set. The figures were released on June, 2011.
During the time of the last sets release, Square-Enix Products shop did an offer that whoever purchases Snake or Miller from their store received a limited edition accessory pack containing the Love Pack cardboard box to display the figures in. The offer was exclusive only to Japan and available throughout June - September 2011.
3 limited edition figures were released for the Metal Gear Solid: Peace Walker set. The first being the ZERO version of the Snake - Sneaking Suit ver. figure. The difference is that his suit is now chrome and the Ballistic Shield is colored orange. The figure is limited to 500 units worldwide and was sold only at certain conventions throughout 2010. The last 2 were the Snake - Battle Dress and Kazuhira Miller Premium Versions. These figures were only included with the Metal Gear Solid: Peace Walker HD Edition Premium Package. (Except for Miller who was only obtainable via Konamistyle.) The difference between these and their original is that they were chromed.
Next set was announced in late 2011 to be Metal Gear Solid, when prototypes of the Cyborg Ninja, Meryl Silverburgh, and Solid Snake was posted up on Hideo Kojima's twitter and released as part of the 25th Anniversary. The ninja was the first to be released on February 2012, coming with his kantana, arm cannon and a changeable hand. Snake came out a month later, equipped with a SOCOM, Suppressor, FAMAS and a pair of changeable hands.

The figure came with the same as the original except with the inclusion of a changeable head. The figure is limited to 500 units worldwide and was only sold at conventions and exhibitions throughout 2012.
