The rarest drops are Mystery Boxes which, when opened, will give you a random super rare mystery item, or if you're extra lucky you might even get one that has a special effect like fire or sparkles! These require a key to open which cost $1 or your currency equivalent, and are a new way to help support the game if the Gold upgrade price seems a bit steep. - Description on the Steam News Annoucement
Mythics are effects in Unturned that are applied to rare cosmetics. They were released in the Steam Economy update.
Mythical items can be obtained by opening Mystery Boxes which are given as an in-game drop. The player then must buy a key to open the Mystery Box. After opening, the player has a rare chance of getting a mythical item. There are 25 mythical and 2 standard effects available for cosmetics so far.
- Holiday Spirit
- Blood Sucker
- Similar effects are found in Team Fortress 2's "Unusual" hats, which are also found in similar crates.
- Rainbow and Divine effects have been removed, they are unobtainable from drops. Purchasing them off the steam market place or trading are the only ways to obtain them.
- The Holiday Spirit mythical is only available from opening a Festive Gift Present, however for a short time it was possible to obtain it from opening a Hawaii Map Mystery Box, but was quickly removed. The items from the Hawaii Box that were obtained during this time were not removed from the user's steam inventory and are still wearable in-game.
- The Blood Sucker mythical is the only player-made mythical and was added to the Halloween Gift Present in 2017.
