After the Master Chief and the Arbiter escape the Flood, they discover that a new Halo is being built to replace Installation 04 which is nearly complete. The Master Chief decides that the only way to destroy the Flood was to activate the newly built Halo, which was out of range of the other installations, with Cortana. The Arbiter leaves to gather the surviving forces and get them ready to leave, and the Master Chief heads to the crashed High Charity to recover Cortana. After wading through tantamount to infinity of Flood, he recovers her and escapes to the new Halo with the Arbiter. Mirabella, Fran (May 24, 2004). "Halo 2 Multiplayer Hands-On Vol. 4". IGN.

[241] Slipspace is the primary method of faster-than-light travel in the Halo universe. Humans have not exacted the science of Slipspace jumping, and can often end up hundreds of thousands of miles away from where they want to be, and therefore they work to be inexact, so as not to end up somewhere like the middle of a planet. The Covenant had worked a way around this, as they can pinpoint jump anywhere in the galaxy, even maintaining their formation. The Forerunners had a superior understanding of slipspace technology, being able to create technologies which allow for manipulation of space-time through slipspace. One of many technologies created by the Forerunners is slipspace translocation, allowing near-instantaneous transit over short distances. Bedegian, Louis (February 13, 2009).
