- "It is a full moon! I have turned into a robot again! Awoo-ooh!"
- ―The Soldier
The Full Moon restriction was introduced with the 2011 Very Scary Halloween Special. All previous items that were restricted to Halloween were updated to be equippable during both Halloween events and full moons. The items will be available for use during full moons according to a formula that closely approximates the lunar calendar. During this period, the main menu background becomes a full-color image of Double Cross, the menu class portrait will be sometimes wearing their Halloween Costumes, the default Message of the day states "Welcome and Enjoy the Full Moon!", and Strange weapons equipped with Strange Part: Full Moon Kills will be counting the kills performed under the timespan.
