Trivia
The Frost Invasion Event was the first event to be released alongside another event, that being the Metaverse Champions Event.
This and the Metaverse Champions Event are the second pair of events to be playable at the same time, the first pair being the SFOTH Event and the Area 51 Event.
This event was originally called the Winter 2020 Event.
However, due to delays causing it to be released in early May, it was renamed to the Frost Invasion Event.
This was the longest running event in the game, surpassing the Halloween 2020 Event on the 15th of November 2021. It was available to play for 210 days.
This event was later remade as the Operation I.C.E Event.
In the game's lore, the events of this event are no longer considered canon as they have been replaced by the Operation I.C.E Event.
Prior to the 16th of May 2021, the amount of Shards gained on each wave were:
