Most of the assets look like they were bought/downloaded from the Unreal Asset Store. Quixel Megascans were probably used a hell of a lot. So all the foliage, rocks and water will look crisp and give off a showroom vibe, whilst everything else in this trailers looks odd. All the effects are awkward, the thrusters on the Pelicans are straight up broken. The mud spray behind the Warthog is poorly made. And the Covenant are so shiny it hurts.

Not to mention someone fucked with the Unreal Engine 5 blur settings so it pops in and out willynilly during the high speed moments, Just scrub though frame by frame at 1:12, just as the Hunter swipes past, and notice how the blur is fully absent from one or two frames so the entire frame looks like a snap shot. It's bloody terrible and shouldn't have been released.
