This set is quite a departure from sets in the past. It’s more an homage to the Halo section as seen at Halo Outpost last year than anything else. Perhaps, just this section is where much of the action will take place in Infinite? At any rate, there is something uniquely cool about this set.

For one, we get to build a very nice stand for it. This is definitely not the norm for a Halo Mega Construx set. I’m LIKING it very much!

The ring section is built from three smaller sections. Each having their own visible differences in topography.

The set is held aloft the base by a small series of pins and clasps.

Here are a couple more views of the set from different angles.

Now, just incase you are wondering, “Can I build a full ring out of multiples of these?”
The answer is yes, sort of…
IF my math is right, the angle at the end of the section is 27°. This would mean you would need four full sets and a fifth partial set. However, the ring would be incomplete.
Three grey sections make up one set. the section in red is one from a fifth set. The gap is created due to the difference in angle. Had the angle for the end piece been exactly 30°, we would have a nice clean ring to make from this set.
Now please, take THAT with a grain of salt as my math may be incorrect. We’ll have to hear word from Mega on this.

At any rate, I plan on getting 4/5 of the set to make a fuller ring. I’ll use pieces from the bases to fill in as needed.
