From Halo Wars old figs to now the product line has advanced considerably that it always beats my expectations. I mean we just barely got super pose able grunts molds which I am rather pleased, and they resurrected the ODST drop pods of amaze that is just hitting store shelves.
They went out of their way to make 2 new gen styles of Recon. Halo 3 gen recon as seen in UNSC Gungoose Rampage. and the Halo 4/5 gen recon seen on Fireteam Stingray, etc. That alone is dedication to the detail of not rehashing the same helmet mold that was just newly made for the same armor.
Art detailing has also tremendously increased. Looking at all the Warzone REQ weapons that come in the fireteam Osiris, Blue Team, and the Halo Heroes series. The attention to detail was better than I anticipated. The High Five Rocket Launcher from Blue Team has in all of its detail, the military logo of UNSC printed in equal size to the guns proportions. They're not stickers either which is the best part.
