Data Hive

Data Hive is a Halo 3: ODST level.

Summary
The level begins as the Rookie, having followed Dare's distress signal, descends down a subway elevator shaft, into the Superintendent's Data Center deep under the city. He ends up on sub-level 7 of the complex, and has to fight his way down to sub-level 9 where Dare is currently holding out. Upon arriving there, they fight their way through a Drone hive to the core of the Superintendent to secure its core data. Inside the data core, they meet a Huragok who has combined the Superintendent's data with its own, making it extremely valuable. Buck then arrives at the complex, and they escape to the surface through heavy Covenant resistance.

Trivia

 * At one point in the level, the player will encounter an NMPD officer. The Superintendent is seen acting strange towards him, such as not opening data stacks for him to allow access or saying phrases like "Warning: hitchhikers may be escaping convicts."(A possible reference to the level The Maw in Halo: Combat Evolved).
 * If 29 of the Audio Logs haven't been found, the cop can be killed by Drones, but if the player has found them, he will lead him to a normally-locked room; he will tell the player to wait outside, but if followed, he reveals his team's purpose of being in the data center: They were under orders from Commissioner Kinsler to kill the Huragok in the Superintendent's core and recover the core data. He then tells the Rookie that he knows too much and that he must be eliminated by the Death loop; Making this character the first non-UNSC affiliatted human ever to have to be killed in a Halo game. After the player kills him, the Superintendent will say "Crime doesn't pay".
