Boulders

The boulders are a collection of large rocks within Tier 2 of O.V.E.R., next to a fence separating Tiers 1 and 2, and have centered in several different plots. Though the complete details of their intended purpose are still largely up to speculation, they are associated with the destruction of 357A. A code can be entered into the boulders through either a specialized device or, more crudely, using one's body to complete an electrical circuit.

Mike's first interaction with the boulders involved entering numbers taken from Ryan through repeated electrical shocks. This led the Flinchites to believe that Mike had access to the tool to insert codes in a safer manner. They also accused Mike of colluding to enter passwords simultaneously with another individual at a different site.

The Flinchites would later force Mike to record a tape instructing Edgar to take a device from a warehouse behind building 116E and connect it to the boulders. Mike first believed that this recording was intended to be intercepted by the Arbiters, but this turned out to be deception on the part of the Flinchites, who did in fact send the recording to Edgar. Without correction, this would have resulted in Edgar's death.

Directed by a future Anne, Mike then broke into Tier 2 and destroyed the device port and power supply next to the boulders. However, these were both found to be unharmed the following night, when Anne, Edgar, and Mike entered Tier 2 to interrupt the Flinchites' and Arbiters' plans. During this event, Edgar is teleported away for full year from his perspective, and returns with Marissa through the Tier 2 fence. Edgar then interfaces with the boulders and transmits data towards Tier 3. This, as he explains, somehow enabled or initiated the destruction of 357A.

The boulders became the target of a mission by early Base, which sent O.V.E.R. Mike to attach a device to the boulders so that Base could collect the transmitted data. During this mission, O.V.E.R. Mike was spotted by Ravi while traversing the fence.
