Floating assault rifles

In the level 343 Guilty Spark, it is possible to see an easter egg that are two floating, firing assault rifles.

Procedure
After you get off the Pelican, quickly run to the area in which you go into the structure with the Flood. When playing the level normally, you would eventually see several Covenant running from Assault Rifle fire coming from inside a structure. Go around the level area and you will eventually find yourself above this structure. As the firing begins, jump down and enter the structure and you will find that no one is holding the assault rifles. The explosions are not caused by frag grenades either, rather they are spawned effects. This saves a lot of time instead of going through the entire swamp.



Alternative
An easier way to get to the floating assault rifles, is to either: 1. Go to the front of the Pelican, and there should be a big rock. Jump on the rock, and from there jump onto the nose of the Pelican. (Do this quickly before the pelican flies away.) Now try to stay in the middle of the top of the Pelican because as it flies away, your character will stay in the same spot. Keep moving around the Pelican so you don't fly off. Wait until the back wing is close enough to the cliff nearest to the Pelican, (this will take a few tries so just keep respawning back to your last checkpoint if you fail.) and crouch jump onto the cliff. If timed correctly, you should NOT slide down the cliff.

OR

2. When you are sitting in the Pelican at the beginning of the level, keep throwing grenades around and you won't jump out of the Pelican. Then the Pelican will fly away the same way it does in method 1, and eventually it will stop and you will automatically jump out and you will be on top of the map where you can easily get to the entrance of the complex where the Floating Assault Rifles are.
