Its been awhile but i think i basically kept running out of ammo in the library level requiring me to have to rush headlong into them to wack them with the rifle butt in order to pickup their ammo. I think i had a terrible weapon combo for that section consisting of the pistol, shotgun, and rocket launcher. Caused me to die a lot. Got tedious really quick.
Hm... I've not had that problem in The Library in particular... You really only need the shotgun and a backup weapon (assault rifle) for cleaning up the leftovers when you need to reload the shotgun. I've found that on Legendary or Heroic, the Flood tend to carry more shotguns too, so once you pop them, it's ammo haven (at least 12 rounds per dropped shotgun). It also helped that you carry 72 shells and that they did a ridiculous amount of damage to the Flood. Of course, on legendary that just means you'll die in one direct shot from them.When im facing levels where im going against seemingly endless waves of enemies i want them to throw ammo at me like its confetti.
I guess the experience varies...
Well, from what I recall, Halo:CE's development was quite rushed towards the end and the Library itself was one that kept changing due to hardware constraints; those blue glowing panels you see from time to time along the hallway were supposed to be more interesting things to give an idea as to why the level is called The Library (genetic repository of some such).Those are two instances of simply really poor QA in my opinion.
That's not to say it couldn't have been better.
