What if weapons and gear found in the radius had a chance to spawn with a randomized anomalous buff/debuff, something you couldn't know at first but could with more ussage. A tooltip on the weapon info can alert you that the weapon has an anomalous property that'll only reveal once you use it. Properties could be proc'd every odd, even, or numbered shot. Properties could include:
-Every proc'd bullet fired doesn't consume ammo
-Every proc'd bullet fired splits into two bullets
-Every shot is angled by (blank) degrees
-Enemies viewed through the scope/sight of this weapon are invisble
-Every proc'd shot hurts you for 1 damage
-The gun has the wrong firing audio
-The gun only fires when it's on 'safety'
-the proc'd bullet will alway richochet towards you/an enemy
-the gun won't fire but will instead eject the round
-bullets fired from this gun glow a certain color for a few seconds after firing
Plus watever other effects you could think of and randomize. This will turn every found weapon into either your new dream gun, or a curse
