Weapons disappearing.

Why is it that weapons disappear so quickly upon player expiration?

Watch your weapons after you die. They just… Vanish. Even if they have ammo.

Same in Spartan Ops, dead enemies weapons will just vanish. Not due to the disintegration effect from promethean weapons either. They’ll be there one second, then… They won’t be.

Anyone have an answer? If this was meant to be in the game I’d like a reason as to why.
