Like, unique looking weapons and armor with good stats that only spawn once per map in special PoI's like museums and secret weapons factories. Make them extremely difficult to find. Examples: a WWII hero's M1 Garand. A civil war saber. Baron Samedi's tophat. Prototype body armor. A celebrity chef's cooking pot. You can't craft these items and their unique models and stats aren't available anywhere else. Make about 20 or 30 of them and then just scatter them across every RWG map occurring only once per seed. The unique model and appearance is very important because it really increases its value to the player.
