demonfox13 what you are describing is typical FPS stuff, there is nothing special about it. The guy says his video is on Elite difficulty in the comments. And you basically admitted that you didn't play much Halo SP, so how would you know if it's any good? Try running and gunning on Legendary (SP not CO-OP) and see how far you get.
Halo has always been known for the AI, KZ2 for graphics. Play a few more shooters and you'll see what I mean.
