This is my tutorial on how to make a Halo 4 Master Chief costume/cosplay. The main building material will be EVA foam and craft foam for details. The EVA foam can be bought almost at all home improvement stores and  the like. I will be using 1/4" EVA foam from a foam shop nearby. The craft foam can be found at Michaels, Ben Franklin and other craft stores.
The other materials/tools are
-A carpenters knife
-Hot glue & Glue gun
-Paper, pens, ruler etc.
-Spray paint-Krylon Italian Olive
-Small lights(led's or miniature christmas village spotlights that can be bought at miachels around christmas time.)

Step 1: Guide Pictures/ Objects

Picture of Guide Pictures/ Objects
Instead of using pepakura, I made all the parts from scratch as I found out that pepakura is insanely complicated. Though pepakura can be useful for guide pictures/models. After my computer crashed on me, I went to use a master chief action figure that worked pretty well.  

Step 2: Making the Cardboard Frames/ Templates

For the Chest/ Torso I made a cardboard model of the piece first to make sure that it fit ( since I don't have unlimited EVA foam) then traced out the pieces onto the foam and assembled. With the helmet I made a base piece out of cardboard that just added durability/ stability then added craft foam and EVA foam to complete. For the cardboard frame, I made small(ish) boxes to hold the lights in the helmet.

Step 3: Making the Rest of the Armor

For the rest of the armor, I made the base piece(s) out of EVA foam and the details out of craft foam. As an example, the thighs were one piece of EVA foam just wrapped in a circle.

Step 4: Spray Painting

Just an FYI if you don't already know, spray paint fumes are toxic (if you don't believe me, I killed a spider with it!) so proper safety gear is a good idea. This includes a natural vapors mask and safety goggles. Also ventilate the room well. Ok enough of the blah,blah, blah. I built a simple painting rig made of a wooden dowel taped to the top of a large bucket for those round pieces like the forearms and thighs. For the rest of the pieces, I just put them on the ground. (If you didn't read the list of materials, the spray paint I used was Krylon Italian Olive.)

Step 5: Extra Details and Water Proofing

You can add other details like the 117 and scratch marks. These were made by taking a coarse brush, dipping it in silver paint, lightly brushing it on a piece of scrap paper until the paint marks are like scratch marks or desired look. To water proof the entire thing, I used SOFSOLE Water Proofer (invisible, works UBER WELL, I mean it water proofs frkin paper towels!)

Step 6: Done!

I made it already, just look on my page

The helmet's "nose" area is a bit too fat to look like master chief.

I also REALLY enjoy parkour, so I might design it with mobility in mind, and do some parkour in it!

On the Master Chief armor you are lacking the "puppy dog nose."
Duct-Tape-Master (author)  Plo Koon1 year ago
I know, the visor is quite weak so I can't push on it and I had the visor in before I realized that I was missing the "puppy dog nose" :-(
is it possible for you to make an instructable on Carter's Helmet from Reach?
i've been building Carter for the last week and it'd be very valuable to me to know how to make the helmet. cheers, Ben

Although, I will make an instructable, if you want me to.
please do :)
What I would do, looking at Carter's helmet, is make the parts that are outlined in yellow in good, 3D detail out of cardboard. Then make the part that is outlined in green out of 1 wraparound piece of cardboard that connects at the back of the helmet and attach this piece to the top of the helmet. Then add all of the details on the helmet out of cardboard(or foam, but by the looks of it your main material is cardboard.) Then paint and you are done!
cheers man, you've been a great help. i finished up yesterday and the results are amazing! i'm starting a 2006 Cyberman after Christmas.

cheers Master Plo.
i finished the Armour Yesterday at 10:23pm

Well for my helmet, I made the top first out of cardboard for stability, and then made a simple sheet of cardboard shaped to be the bottom of the helmet, and put the details on in foam later. Just ask any questions if you have them.

can you make a tutorial for the helmet pleeeeeeeeeese???
Duct-Tape-Master (author)  jackmaster1 year ago
Maybe in another whole instructable if enough people ask. :D
Can u Make a tutorial of all good guns :
Plasma pistol
For the shotgun and other larger guns, use my assault rifle or battle rifle method. For the pistol, use DaFrontLineTrooper's pistol tutorial. For the plasma pistol, simply carve the pistol out of a block of foam. Trace out the shape of the pistol with a knife in the foam, then use the knife to carve out the details. My pictures are attached to this post.
