On mission 5, “Reclaimer”, the giant truck you’re on arrives at a clearing with several ghosts and a wraith. To your right, a larger covenant dropship hovers over a rock mountain, and according to what I’ve seen when I looked this up on youtube is supposed to drop a green tractor beam to suck you up into the ship. Guess what happens for me? No tractor beam. I tried clearing out all enemies and they just all spawn back in. Anyone else experience this? I’m starting to get very frustrated.
IIRC, my friends and I had to pull a Warthog out from the bottom of the Mammoth to get the scripting to trigger for having that ship hover over the rocks and deploy the troops and the tractor beam you’re looking for.
Hope this helps. 
Hey man thanks. The problem is that the ship does come and hover but doesn’t drop troops or a tractor beam so i have no idea what to do…
Try getting on a rock (or warthog) then jump and jetpack, as there are places on the sides without walls. Or else try reverting to save if you haven’t.
It’d appear all those Ghosts and Wraiths are infinitely spawning. You’re not required to engage them.
Yeah everything is definitely infinitely respawning. I tried reverting but it doesnt bring me back far enough. I think i’m in trouble…

As I don’t have the game yet, I’ll just leave this here:
Have you tried dying 5 times really quickly? That may take you back to the second last checkpoint.
Have you tried this guide?
If you want a really quick way of completing the level, wait for Nak3dHalo to upload his level guide.
I’m having the same issue. I’ve redone the mission three times now. Each time I don’t get the tractor beam. I’ve moved around all the vehicles and tried starting up a script and nothing happens.
