HALO

In the year 2291, the United Nations Space Command (UNSC) successfully develop humanity's first Slipspace drive, the Shaw-Fujikawa Translight Engine. For the first time in history, the rapid colonization of other worlds is made possible. By 2390, 210 worlds have been occupied by humans, and are being actively terraformed to suit man's needs. These worlds are to become known as the Inner Colonies. By 2490, the UNSC's fledging interstellar empire has expanded to over 800 planets throughout the Orion Arm of the Milky Way Galaxy. During this period, the planet Reach becomes the headquarters of the UNSC military, and is destined to become the most heavily fortified world under human control. By 2517, several years before contact with the Covenant was made, the UNSC military embarked on a secret project to create a group of elite soldiers that would deal with occasional unrest in the Colonies. Codenamed SPARTANs, these genetically enhanced troops were trained from the age of 6 into a life of battle, and became a great asset against the Covenant. While humans suffered defeat after defeat in space, they could almost always prevail with the help of the SPARTANs in ground engagements. The main character of Halo's gameplay, the Master Chief, is a veteran SPARTAN of the SPARTAN II project after an unfortunate failure of the first SPARTAN program. All SPARTANS were given special armor designated MJOLNIR, which can increase their strength and speed. They were the only ones who could wear it as those without upgrades would be thrown into convulsions and die. By 2552, many of Humanity's Inner Colonies have been destroyed by the Covenant. In a move of desperation, UNSC orders a secret plan to capture a Covenant ship using a SPARTAN task force and find the coordinates of their home planet. A group of SPARTANs, led by the Master Chief, are chosen for this mission, and board a specially outfitted ship known as the Pillar of Autumn (under the command of Captain Jacob Keyes). This plan, however, is interrupted when the Covenant launch a surprise attack on the fortress world of Reach. During this battle, Reach is overrun and glassed, and the human fleet is obliterated. Worse still, the Master Chief thinks that all of the SPARTANs but himself are killed on the surface of the planet. The (supposedly) last remaining SPARTAN, the Master Chief, escapes with the Pillar of Autumn. In accordance with the Cole Protocol, the Autumn makes a blind Slipspace jump, and emerges in the vicinity of an unexplored and remarkable world. The Pillar of Autumn exits Slipspace to find a mysterious ring shaped space station orbiting a Gas Giant. The ring, quickly named "Halo", is obviously artificial and teeming with life. A Covenant fleet, however, is also present, and a subsequent battle heavily damages the Pillar of Autumn. Captain Keyes initiates the Cole protocol - all records of Earth's location are erased, and the Autumn is crash landed onto Halo. The ship's AI construct, Cortana, leaves the Autumn with the Master Chief in a Bumblebee escape pod which also crash lands on Halo.
