Building a Better Spartan – Foam, Tactics, and Concept Art

Hi all!
Been lurking for a bit — I’ve been wanting to get back into Halo stuff for a while now. This will be my third suit (last one was my Guardian from Destiny), and I’m finally diving back in with something I’ve always wanted to tackle: Reach-era MkV.


I’m notoriously bad at finishing projects, so I’m posting here for accountability. But also to share some progress and maybe even help some folks out along the way by sharing some of the files I make and anything else of use.

It’s been a few years since I last built anything, so it’s good to be back covered in contact cement and foam dust again. I’ve been making decent headway, but held off on posting until I had something worth showing.





The Plan​


I’m building a Reach-style MkV suit — mostly inspired by Isaac Hannaford’s concept art. A bit more tactical and grounded than the final game assets.
I’m swapping in the Air Assault helmet (personal fave), and I’ll probably keep adjusting small details as I go.


Here’s the rough idea / aesthetic target:
1736823849231.png






Priorities​


#1: Proper scaling.
That’s been the weak point in my previous builds. Everything looked just slightly off — like I was wearing cosplay made for a bobblehead. So this time I’m laser-focused on dialing in proportions. If I have to rebuild something (and I already have), so be it.


The ultimate goal is to end up with something movie-quality. Not screen-accurate necessarily, but solid enough to pass for a prop on camera.
That means I want your feedback!!! If something looks slightly off - let me know! I want this thing to be the best it can be!!!


Bonus goal: build this thing completely in secret and surprise friends/family next Halloween with my Spartan reveal.





Starting in Armorsmith​

1736824819818.png



Started mocking things up in Armorsmith to get my scaling in the ballpark. Love the tool. Great for layout and visualization. I am, however, very dumb, so user error is a recurring theme here. (More on that when we get to the chest piece…)





Thighs First (For Some Reason)​


Because logic is dead, I started with the thighs. I didn’t love the available pepakura models and preferred the shape of the Infinite-style thighs, so I freehanded a set of thighs based on my dimensions in armorsmith to get something rough.

I’m happy-ish with the look, but I think they’re a little underscaled. Might rebuild. Still on the fence. At least I saved the paper mockups and might digitize/scan them for templates.





Helmet Time​


1736824614076.jpeg

Printed the Air Assault helmet. Two and a half times. For sizing. Yeah.


Finally nailed a snug-but-comfy fit. First time trying the plastic welding seam technique with a soldering iron (bought a cheap one just for this). Worked surprisingly well. Solid seams. Should clean up fine... once I finally stop putting off sanding. (I will continue putting off sanding.)




Chest, Version 2​


1736825571325.jpeg
1736825587959.jpeg

So. I made a chest piece. It was 5% too big. I made another chest piece. This is that one.

Honestly, building the too-large version first helped — good practice, and I’ll use it for sealing/paint tests later. This newer one feels right, and I’ll be building out the lower rib armor next to nest underneath.


Once that’s done, I’ll move on to the biceps and ODST-style shoulders — templates for both are sitting here on my desk, judging me.





What's Next — And Helping the Community​


One thing I’m doing differently this time is building and refining my own templates as I go — especially where I’ve freehanded or modified designs based on concept art or in-game models.


If I can get clean enough versions of my paper patterns and foam cuts, I’ll be scanning them OR turning them into pepakura-friendly files for others to use. Especially the Infinite-style thighs, which I haven’t found solid templates for yet.


So if you’re into custom Reach builds with a slightly more infinite feel, stay tuned — I’ll be uploading my files once I clean them up.





And Now, A Weird Pose from Yours Truly:​

The build’s coming along. Fitment is feeling good. I look professionally awkward and i'm here for it.
Thanks for looking — more soon.

Nice!

I know literally nothing about Foam, actually only ever made a gauntlet for Dragon Age out of foam..

However, I know the feeling of starting a lot of projects and then... Well time passes

Your doing a great job, luckily for you... We have some amazing Foamsmiths in the 405th, so your in great hands.

However, after more thought.. thanks for inspiring me to gander at foam again for a future project!

Keep up the good work!

Foam is life! I love the stuff. Some people are very good with it. I'm a little rusty. A great medium, though. Definitely worth giving a second shot!
 
Yeah, I love working with it. It can be a pain sometimes, but the satisfaction you get when you complete a piece is just so rewarding.
 
Bicep update.

I started out with a foam unfold that I found in the armory. I took a crack at building that one but wasn't happy with how things were looking, I think the other model was more intended for papercraft.

So i ended up remodeling it in blender, correcting some inaccuracies, and modeling it to be a little more foam friendly:

1737317451931.png

and it was ready to be unfolded.

If there is any interest in these files i'd be happy to share them, they've been battle tested but I will make some revisions to the unfold so they're a little easier to work with.

Anywho, new templates were a success. Pretty tough build, actually. Definitely not perfect but certified good enough. And they fit pretty well. More on that later.

So yeah, onto the other bicep and then the shoulder pads themselves.

Plenty more coming. I just finished up my waist armor model, so that'll be built soon, too.

Til next time.

Your foam work is so clean!! Can't wait to see more, I never get tired of Reach armor. The redo of the biceps looks great, the base files we have here are super helpful but never exactly like I want them lol, they're never quite fully accurate.

Thanks! I was actually looking at your reach build from a few years back when I was planning this one. It looks sharp!



Moving forward with the build...

I am looking for some scale feedback!

I recently built my bicep armor and a shoulder pad. I think I may have scaled them too large. I'm not as concerned with the bicep as I am the ODST shoulder. But I appreciate opinions on the scale of both. Brutal honesty is acceptable. Thoughts?
1737864259522.png
1737864469259.png

My gut tells me both are a smidge too big. The ODST shoulder definitely. I'm beginning to think my print settings are goofed up, everything seems to be coming out about 5-10% too large. Fard.

Anywho. Glory shot of the ODST shoulder. This may be the last time you see this guy before he's replaced with a better, 8% smaller younger brother.

Thanks for looking. LMK your thoughts on the scale of everything.

Til next time.


EDIT. Here are some references I've been using to help me with scale.

Foamsmithing is top notch mate, I'd say, just nit picking here really, but if you slightly lowered the shoulder position on your arm. It might look better? But it does look amazing, maybe slightly smaller odst shoulders though. Keep up the good work though mate
 
its lookin great! i think the scaling looks just fine, personally.
Your foam work is amazing!! That's so clean!
Thanks to you both!

Totally agree. I experimented last night on some fitment changes to make things look better, but I still wasn't happy. I'm committed to making a new one atm. I'm using this as an opportunity to remodel some of the shoulder pad and make some better templates. I like the way that this one turned out but I ended up freehanding a lot. Messing with the templates some should fix that and make it more repeatable. If nothing else it will be another file to add to the armory.
 
This build is looking immaculate dude! I can't wait to see the fully finished thing, those of you who foamsmith always blow me away with your talents!
 

Back From the Foam-Free Abyss​


After several months of hiatus, I’m back at it.

Progress has been made — but let’s keep those expectations low, where they belong.
Home renovations might have taken the #1 spot on my project leaderboard, but this build is still a strong second.



Shoulders, Again​


When I left off, I was running into some classic scaling issues with the shoulder pieces. Since I was rebuilding them anyway, I took a stab at tweaking the shoulder model to make it:


  • More foam-friendly
  • Slightly more accurate to the Halo Infinite version
  • Probably not worth the time, but here we are

1754705550718.png

TBH, this was probably not the best use of my time — the difference is minimal.
BUT THAT’S NOT THE POINT.
1754705646252.png

The new version is about 5% smaller. And slightly more better all around.
That’s… it. lol.
(But honestly? No regrets.)




Waist Armor Redesign​


Then I jumped into the waist armor — and this one actually made a noticeable difference.
1754705833395.png
1754705909369.png

The one on the left is my remodeled version; the right is a commonly found file. Huge difference in shape and proportions.
WAITS.jpg

Still assembling it — but holding off final assembly until I figure out how I’m going to attach this thing to my mortal coil (i.e, me). I’m also planning to 3D print the side pouches so they’re a bit more functional (storage! wow!), and I want to design a mount system that’s adequately usable.





Forearms & Life Choices​

Also started modeling up the forearms, because I’m a professional at making more work for myself:
1754706430336.png

1754706480474.png

Might be a touch big, but I think it'll work out once the full arm is done. Still a WIP — haven’t built out the wrist or inside areas yet.

(Peek the bathroom renovation in the background for bonus context.)

Thanks so much!! You give me too much credit - without pepakura i'd be toast!!!

How’d you get the thigh curve so perfect? I’ve never been able to make that work.
Haha, thanks! If you're talking about the front curve — I basically made sure the front-facing edges that join up had a slight curve baked in.
Here's a highlight of what I mean:
1754707160959.png
Honestly though, I just eyeballed it. It’s not 100% game-accurate, but I thought it’d translate better in real life. Just wingin' it.
Looking good, Spartan — keep up the good work!
Appreciate it!!



Side Note: Paint Scheme Hype​


What do y’all think of this paint scheme?
1754707831887.png

I know paint is still a long way off, but Isaac Hannaford’s concept art is a big inspiration here. The color scheme is...mmmm....very noice— really excited to get to that stage eventually.



Thanks all for tuning in. More to come (eventually — unless my house decides to fall apart again).
