In December, SpaceInvasion 2 usually celebrates Christmas. The event typically runs from early December into January. The team announces the details every year.
Collecting gifts
The event currency is colored gifts: green, blue, yellow and red. You get them, for example, from the Gift-O-Mat, the Christmas calendar and Santa flights – event flights to marked planets in the Galaxy map. In the event shop you trade the gifts for bonuses such as Interdimensional Transmitter free spins, multiple production, shorter construction and research times, the inactive farmer (50 % more loot from inactive players), a fleet construction bonus or 20 % faster recycling, colonization, transport, inactive-attack and event flights.
The gift counter
All gifts you collect count towards the gift counter. Anyone who collects a total of 100,000 gifts may move a planet of their choice (Moving Planets). After that, the planet cannot be attacked for 12 hours, and no attacks can be launched from it for 7 days.
Christmas calendar
From December 1 to 24 you open one door every day. If you open it on the right day, you get the full reward: resources on your currently selected planet, plus for example Interdimensional Transmitter free spins, multiple production for your stock or data disc fragments, and random gifts. You can catch up on missed doors, but then they only give you a resource pack.
Santa gifts
Santa gifts are surprise packages that you send to a friend or to "Santa's children". The recipient can accept or reject a gift. What is inside is only revealed when it is opened.
