Rabbids Invasion (lost Facebook game; 2012-2013)
Rabbids Invasion (not to be confused with the animated series of the same name) is a Facebook game developed by Ubisoft Paris and published by Ubisoft on April 3rd, 2012. On January 28th, 2013, the Rabbids Invasion Facebook page announced that the game will be closed on the February 13th, 2013; the reason for this is currently unknown, but the name Rabbids Invasion had since been used as the title for an animated TV series which aired on August 2013.
The game was set in a world which humans had lived peacefully. The main goal of the game was to invade this world and cause chaos, as well as collect experience and items that would be useful later on. The game had a single-player mode, where the player would pair up with a "fake friend", but there is also a multiplayer mode. In the multiplayer mode, up to 5 people could play in a single game, at which upon completion would give the players rewards. If the player was on their friend's list, they could be invited to the game, give and receive items, complete quests, etc.
The game in it's lifetime was unpopular and there are few gameplay videos online. Ubisoft has never mentioned the game since its shutdown. As of the time of this writing, there is no way of playing the game nor are there any assets or files available online.
