Hey. You may have seen those xenomorph looking things around Blue Team. The first one being the one that spawns the ‘banshee swarm’ at the very beginning. Well, there are four more in the hangar bay when you’re flying around shooting the vents. I found out what three of them do, but can’t find out how to get the fourth one to show it’s secrets. I recorded ALMOST everything I’ve found HERE! I’ll explain some things.
Each ‘xenomorph’ (except for one) gets activated by standing very close to them and holding a specific weapon. When it gets activated, it will spark a bunch and then if you’re holding the correct weapon, a grunt birthday party YAY! will play. What weapon you hold depends on what xenomorph you’re near. When you activate one, an enemy spawns. Each xenomorph spawns a different enemy. One has two elites, one has a banshee and the last has a phantom.
Let’s take some notes.
The elites drop down from above. If you fly up to where they spawn, you’ll find some rockets. This is likely a hint for the next step.
The banshee does not shoot at you. It flies passed you, up a bit, then sharply leaves the hangar bay. You get exactly the amount of rockets you need to destroy the banshee. Could be coincidence. You might not even need to destroy it, but I believe you do.
the phantom is weird. It spawns right below you, pauses for a split second, then flies up toward the center catwalk. It pauses a bit again, then leaves the hangar bay. It doesn’t drop any enemies. It can be destroyed as seen in the video. The pauses make me think it’s designed to let you hitch a ride back to the top, but for what?
No-one’s found out how to activate the fourth xenomorph. I believe the sword will be used in some way since it’s always at that same spot along with the other weapons. In addition to the two plasma pistols found near two of the xenomorphs, there is a third hidden in the back-right corner in relation to the phantom spawn.
Hunt for things in the area yourselves. Maybe bring some friends along! If you find anything, post it here. I’ve spent a good 10 hours working on this egg and I’m stumped and maybe some fresh eyes will help. 
Good luck.
There are large white tanks with darkred stripes on them that can be damaged. From what I can tell they don’t serve a purpose in the mission so there may be a chance they’re linked to the easter egg.
Oh man add me I will gladly help out when I can!
I found three of these things in solo before this thread was posted. See here. I got the first one (the one down on the black tubing with the plasma pistol) to activate with the sword.
Cool thanks. I happened to think one of those was a skull, and then thought “That’s messed up, what’s this for?” when I went in to claim it.
I don’t remember exactly but I think I went sword to the black pipes (plasma pistol nearby), then plasma pistol to the far opposite corner, then I got hung up on the third.
You can find one of these at the very beginning of the level too. Right under the glass looking over the giant hanger when you first start.

If the enemy didn’t spawn you didn’t activate it.
So Zoruku on reddit found that if you hijack the banshee, it turns out it’s an ‘Ultra Banshee’ that fires super-explodey fuel rods! This is pretty sweet. But that doesn’t explain the two other enemy spawns.
Does it let you essentially bypass the level like in other Halo games?
i have tried all the weapons available in that area, and even that special shotgun, maybe its a difficulty thing? or maybe something has to trigger it or something
another theory i have, maybe it require a weapon that one of the other Spartans have, so you would have to try it on co-op

I’ve been told the xenomorphs don’t activate at all during co-op.
I found one of those in the very beginning when you over look the ship thats being taken apart. If you jump onto the pillar to the left and then the platform just below the window and follow the other pillar around you’ll see the skull looking thingy sitting there. Sparks came out of it but didnt hear any sound. Is this one anyone has found and can tell me how to active it??
Haha, that little thing looks like a Xeno plushy, me want!
I am going to dig into this and see what I can find.
What difficulty? Since you can hijack the banshee that activates, that makes me think itcould be required, such as maybe destroying the phantom with that banshee? Activating something? Just throwing out ideas.
