Events
Events are celebrations of the game that involve limited-time maps, enemies, towers, and skins, and sometimes special objectives. They may be to celebrate certain events and holidays during the year, like Christmas or Halloween. Completing event maps may reward you with 
Gold, an event tower, and several unique skins. Some events may be accompanied by a battlepass which offers the latter two. After an event has concluded, the event towers and event skins may no longer be obtainable without the use of 
Robux.
