Glitch: Floating Guns In Quarantine Zone
In the level Quarantine Zone, after the gondola ride ends and the chapter "That Old, Familiar Feeling" begins you might hear an Elite say that he hears something. You might also hear some faint static-like noise. This is the sound of two SMGs firing. To get to the source you need simply to get to the gondola the Humans were riding. The easiest way I found is to go to the end of "your' gondola nearest the gondola the Humans rode, and grenade jump from the rail to get on the structure in which some of your elites stand.

Now, jump off this structure towards the part of "your" gondola that is nearest to the "human" gondola; be forewarned that the wall toward which you are jumping is fake, and you will pass through it. Make your way from the beam of "your" gondola to the beam of the other gondola via a jump. Now you need to grenade jump over a wall to be on the main part of the "human" gondola.

As you near the exit of the gondola, and begin to enter the Library where you find a dead human you hear the static sound – the sound of SMGs firing. As you walk toward epicenter of the sound – the door leading toward the centre of the Library where the Index/Sacred Icon is found – you will see two SMGs floating in midair and firing – does this remind anyone of the level 343 Guilty Spark in Halo? You can "Hold X to swap" and the gun(s) will continue to fire in your hand. It only has one clip, so after a few seconds of it firing you just hear the trigger being pulled.

You can also juggle the weapon toward/through the door and have it shoot at you in the cut scene if you so choose. The gun fires throughout the entire length of the cut scene. Your previous weapons will not, however, hover and shoot like the SMGs you swap.
