Halo 5: Blue team mission Mystery

Someone on Reddit noticed something interesting on the Level Blue team in Halo 5. Linky to Reddit post.

There are these 4 cases hanging above the area you first battle Hunters in the level. In these cases are unknown at the moment. But there is something unique in them

I have a mission for the lore community. We need to get a clear view of the mysterious objects/creatures. And screenshots of them lit up with light.

We need to somehow get light into the cases. I suggest going into teams of 4, with us all holding weapons that can light up the case. So hopefully we can get a view of the creature.

Weapons that create light.

• Shotgun(plus hidden shotgun)
• Plasma Pistol
• Energy Sword
• And at a push the Storm Rifle.

Lets solve this mystery or get to the start of it.

I saw the post, pretty intriguing stuff. Do we have any reason to believe it's not just a blank texture? I play with the brightness almost all the way up and nothing. I mean I don't think 343 would have a potentially huge discovery be even possible to identify completely, even if it was hidden.

Well we could try getting in a 4 person team and using light sources as I suggested. I mean. That is our last hope outside asking 343i for a clear image of it.

Looks like this to me: http://www.halopedia.org/images/b/be/Paelosur1.png
However, the guards who dropped the weapons that you can pick up throughout the mission seem to be in defensive positions, and if you read the comments on reddit it's possible that it was some sort of zombie thing. But Halo already has the Flood, and while it isn't quite zombies it's close enough and Halo doesn't need a different kind of zombie thing like that.
But hey, anything is possible.

"Cell storage"... Looks like it's a creature.

Kind of creepy.
