The Birthday Party Game was a special Ambush Game that celebrated the games' first birthday. It will be played in June, 2013 and will be hosted by DarthPotato77, who also hosted the first two games. It was Spider's idea.
In order to celebrate the Ambush Games' first birthday, DarthPotato invites all of the game players to a big party in order to celebrate the occasion. But things soon go dark as people start being murdered. Potato and everyone else know what this means: There are scum amongst them. Now, The Ambush Game players, lead by Potato, must use all of their skills and wit to find the scum traitors. One year and 17 games have lead up to this, now it's time to see who will truly prevail.
