Here's my message to the designers of MCX: Has your team taken into consideration changing the leg design for Halo Infinite marines to make them more to scale with the Halo line? Perhaps making shorter call of duty legs, using the NMPD legs, or something else? I really don't mean to sound whiny, it's just that proper scale is a very important thing to me as a collector. By the way, apart from their leg design, the new Infinite marines are such great figures and quite probably the best marines you've made by far.
Now, for anyone with Infinite marines who stumbles upon this post, I've thought of a solution to make Infinite marines a little shorter if you want to try it. I took the upper legs of Halo CE marines, then the black lower legs of ark marines and put them together to make a decent looking Infinite marine. To be fair, this is kind of a costly method because you need to buy multiple figures to pull it off, and it's not 100% accurate to the in-game marines. But aesthetically, it looks pretty good, and I so happened to have a bunch of Halo Wars marines and CE marines lying around.
Sergeant Forge and series delta marines could also work because they too have light green thighs, but they're very hard to come by these days. Clash on the ring blind bags are still in stores as of lately, so it'll be much easier to get a whole lot of CE marines. Although I can't say how longer they will be around, given that the new Halo Infinite blinds bags are starting to turn up, so get some while they're still available!
