The Keeper 1.0 is a S.A.A.T. version of Guardian 1.0, released 13 Feb 2012 in DLC form, along with patch 1.03 during "The Eden Project" World Event. It can be unlocked with all upgrades through Steam Store for $1. The Keeper 1.0 features an unique appearance and item description, and is classified as a Tech building (unlike Guardian 1.0, which is flagged as belonging to Eco faction), making it useful for Ark builds centered around Techs. Keeper 1.0 can be very useful to some players, who missed "The Eden Project" event, for those who can't beat 3rd event mission, "Against the odds", because of its difficulty and wants the Former technology fully operational with all its upgrades, or simply to those who want to collect every building in the game.
Despite the fact that Keeper 1.0 and its upgrades have identical construction costs to the Guardian 1.0 and its upgrades, there is actually one difference between them. Guardian 1.0 Automation module requires the Trendsetting molecular motion sensor prototype when its analog, Keeper 1.0 Automation module requires the16-step safety system prototype.
At 500% efficiency, the Academy takes 5 minutes to complete the module. However, any of its upgrades will need 24 minutes each to construct.
