I noticed something that is pretty alarming about the first mission of Spartan Ops episode 7. I replayed it on my own to kill some Prometheans Knights and noticed that all the AI corpses were disappearing almost immediately after death. Then I had instances where as soon as my final DMR shot landed the enemy Elite vanished right in front of me. I wanted to get another Elite's Sword but it, along with his corpse, disappeared as soon as they touched the ground. How crazy is it that a Halo game is making such great sacrifices for pretty graphics? That area, Apex, isn't even impressive. You could see the seam between some of the ground textures, the environment textures are also a little muddy, and the skybox and geometry in the distance is very simple and uses even lower-res textures. What the hell is stretching the engine so thin in Spartan Ops? It's terrible.
Man, I want Halo 5 to be good. I just hope they don't sacrifice so much for pretty aesthetics. Give us good UI, proper MP, and for the love of God make sure that weapons don't disappear in 2 seconds and eliminate all texture and geometry pop-in. It's a little bit disorienting to see textures and environments pieces (like a large boulder) pop out of nowhere.
In other words, make sure it runs as well as Reach did.
