Portal:Timeline/Extinction

A timeline of events in the "Extinction Timeline." It features events from the Extinction mode from the Call of Duty series in the game Call of Duty: Ghosts.

Long before modern life
A dark planet covered in volcanic ash is hit by a comet that incinerates everything that lived on the surface. The Cryptids survived by living underground where they evolved and advanced to survive in harsh climates and underground life.

One year before the outbreak

 * Samantha Cross is a student at Harvard before she disappeared.

2016

 * The ODIN Weapons system in space is attacked by the Federation and is hijacked. Kinetic Energy Missile rods are then launched and destroy the majority of the south/western United States. However, two surviving American crew members, Mosley and Baker, fight back and scuttle the space station before the remaining rods are launched on the remaining U.S. cities, but sacrifice themselves in the process.
 * During the ODIN strike, David Archer and his team find a hidden carven in Colorado and get as much Cryptids as they could get.
 * A missile makes impact in Colorado, allowing underground Cryptids rise up and attack the state.
 * While on a mission at a small town destroyed by the ODIN strike, four soldiers; Miller, Williams, and two others, stumble on a dead human feasting site and are attacked and killed by the aliens.

July 24, 2016

 * A squad of soldiers arrive at a small town and attack and destroy the hives with drills while fighting off countless aliens. They then reach the impact crater where they arm a nuclear device. The squad retreats back to the helicopter while being chased by a massive horde of aliens, successfully escaping the town before the nuke detonates. They apparently destroy the alien threat.
 * After the nuke blows, several scientist smuggle samples out of the area to find out why they are here, where they came from, and what they will do with the humans.

After Colorado

 * A man named David Archer recruits Dr. Samantha Cross to project "Nightfall" in a research base in Alaska, which is a project where they study the "Cryptids" and discover that there are many different types of them, enough to have their own ecosystem. Samantha is hired to figure out an unknown ancient writing.


 * Someone releases the Cryptids, which starts an outbreak at the base in Alaska. Every man at the base is killed during an outbreak except Samantha Cross, who is trapped as the aliens hunt her. They constantly chase and trap her but never kill or hurt her for a currently unknown reason.

14 weeks after Colorado

 * A group of soldiers are sent to the Alaskan base to rescue Samantha Cross.
