I have been waiting a long time to get this since I first heard it was in production around late September/Early October. Then when I saw it in person at New York Comicon last year I just KNEW I wanted this set.

Okay, so there were some snags in this set, which I’ll go over, but stick through til the end. I promise the set won’t disappoint.

UNSC Mantis: Set number 97115

Minifigs: Spartan Warrior (Steel)
Weapons: SAW
Accessories: N/A
Special Features: Opening/Closing top hatch, multiple double joints
Price/Value: $35 US

The price is pretty good for the piece count. I was missing several parts when I checked the pieces against the parts list. Still, I proceeded to put the set together, knowing I’d be calling Mega Brands on Monday to have the missing parts set to me.

Normally that alone would really put me off to a set. However, since I had seen this in person, I knew the set was going to be a fun build regardless of the missing parts.

Without further ado, here is the pictorial review with commentary (click the pics to make bigger).

Box Front

Box Back

Box Contents

Contents of big bag from previous pic upper left

The pieces are sorted

Upper body being put together

Top hatch assembly

The upper body is complete except for a missing part. I’ll make note of that in a later pic.

Machine Gun arm assembly

Rocket Launcher arm assembly

This arm is missing two parts. Again, I’ll make note of the in the next pic.

The circled areas denote where there is a missing part.
• Upper-missing 2X1 reverse slope on the rocket launcher arm
• Middle-missing 2X1 modified double round piece
• Lower-missing “T” piece. This one was a bit critical as not having it makes the arm very unstable. It comes off way to easy without this piece.

Leg Assembly

Leg final assembly

The legs were the same build (just mirrored), so I’m only showing one leg here.

Lower body assembly-missing 3 parts.

I made a slight error building this section. Top row second pic shows 2 elbow plates in the wrong postion. I fixed that in the lower first pic.

The parts missing are:
• Upper left-missing pin
• bottom row second pic-Missing small 1×1 slope
• bottom row second pic-Missing small 2×2 “wing” This is hard to see due to other piece built on top of where it should be.

Large section assembly

Final Assembly

Sorry for the blurry shot here. Some better ones are to follow.

So at this point, I was missing 6 parts. Nothing too major, but the “T” and pin parts are fairly important to the stability of the Mech.

Now on to the Docking Station.

Docking Station build steps

Docking Station Final Assembly

Final set shot.

Now this looks good, however, I’m just not satisfied with the docking station. There is nothing like this in-game. So I took the dock apart and remade it with the left over parts. Speaking of…

Left over pieces

Missing parts list

Damaged bag

Here I found the culprit of the missing pieces. Looks like this bag was crimped at the wrong place as there seems to be a burn mark (top circle). The bottom circle denotes a tear in the bag before the parts were removed. Makes sense as I had some loose parts in the box. I thought they might have just been extra. Turns out they weren’t.

Redux Docking Station

And here is the set finalized with the docking stations redone and the computer station added to, plus the minifig. I like this set up better.
