Halo: Uprising Issue 3

Halo: Uprising Issue 3 was released (after being delayed) on August 13, 2008 and is the third of four in the Halo: Uprising series of comics.

Plot synopsis
In a flashback, the "Key of Osanalan" is revealed to be a fictional object made up by Ruwan Ackerson, and his brother, James Ackerson when they were kids. Colonel Ackerson spoke of the "key" and divulged this false information in order to prevent the Covenant from destroying Cleveland, where Ruwan resided. In response, Covenant forces forcibly assembled nearly all of Cleveland's inhabitants into a stadium for questioning about the Key. Ruwan and Myra are saved by a team of Marines and escape the city in a Pelican, where they tell the Marines what the Key of Osanalan is.

Meanwhile, aboard the Forerunner Dreadnought, John-117, attempting to assassinate the Prophet of Truth, is caught by surprise by a Jackal and shot in the back. He falls many stories before landing in front of a procession of Brutes guarding the Prophet of Truth. While the Spartan manages to get several shots at Truth, the prophet is shielded by his gravity throne and makes his escape, as the Chief is left to fight dozens of Covenant. He kills them all and starts to find a way off the ship.

Trivia

 * The Gravity Hammer Master Chief is holding on the cover is deactivated, since the Hammer is not emitting its characteristic blue glow. This likely means that at some point in the battle with the Covenant forces now lying dead at his feet the Hammer ran out of power and he was forced to use it simply as a bludgeon.
 * In this issue the Brute Lepidus is seen again.
 * The room in which the Master Chief kills a whole pack of Brutes is identical to the Covenant Council Chamber.
