The capsule machine was added to Microvolts on 2011-11-10
It costs 990 RT to spin the capsule once.
You have a chance or either winning an item, weapon or accessory (7 - 30 days) and a rare
The rares are permanent and do not require you to repair compared to MP and RT unlimited weapons.
The rares would consist of 3 types of rares, bronze, silver, and gold for weapons. Sometimes, the bronze can be black and other rares may change color (Ex. Blood D. Fall is a silver sniper that has a red color scheme.) While for clothes it would be a set, however you can only win 1 piece at a time.
Some rares are more powerful than MP/RT weapons while others are completely outclassed by MP weapons alone.
