The original Infinity Shape figures were long sought after, including the two PMC figures and the one with the floppy hat/shotgun and PAGST helmet/M4.
I had those kits. I eventually sold them after years in storage. Even though they were rare, they didn't attract me enough to build them.
The main problem I found with 1/35 Infinity Shape figures was that they were White Metal whereas practically every other 1/35 garage kit company used resin. White Metal is akin to Wargaming figures; kind of soft on the details, smoother, molded on pouches and details, and easy for small parts to bend and break. While they may look nice painted up, in reality, primer and paint sometimes have a hard time sticking to White Metal figures.
Now that Nutsplanet made them (I would assume) in resin, hopefully the details would be crisper. I am surprised though that Nutsplanet didn't include extras or modified them, instead preferring to cast them OOTB as the original Infinity Shape molds.
