|The sword can't be used with the old FG - it doesn't have the peg hole for the mount. Still, it looks like they used the old FG parts as the basis for the weapons systems.|
1) Main kit really is the old HGGS Aile Strike. It has all the old parts for it, with slight recolors - the grey has become Metallic grey, for example.
2) The new parts are minimal, in the sense that there are no extra parts to change the Launcher and Sword pieces into searpate weapons systems (I guess they were happy enough with the RG versions).
I'll be assembling this by sections over the next few days.
