I'd like to view the new Snake figure as an upgraded version of the Sneaking Suit Snake PAK from Peacewalker a few years back and in a way it definitely is. Accessory-wise though they are still both lacking in my opinion but this version takes the cake because of one inclusion which i will discuss later. For now let's see what he's packing:
A Rifle, check. Pistol, check. Knife, check, 3 extra alt hands, check and yeah, there you go, you get an alt head with NVG. I think that's a first for an MGS Play Arts Kai figure and it's a very nice inclusion.
The biggest improvement...errr...should i call it an improvement? anyway, is the new head-sculpt. We get an older Snake here minus his bandanna and sporting a different hairdo and beard. Of course, as i mentioned earlier, the NVG head is a nice addition which opens up more playability and display options for Snake. With the price increase for the newer PAKs i think it's fair enough for an extra HS to be included in this figure.
However, i'm not a big fan of the new HS. I think it's less detailed than that of the older Snake and the paint application isn't that good. The "oily-skin" makes the HS even less impressive so if you have the old Sneaking Suit Snake i suggest you try doing a head-swap when displaying.
