United Nations 2

The United Nations 2 (UN2) is the player's faction and the source of most of the units available in Strain Tactics. The player is revived at a UN2 facility and tasked with clearing Strain wherever present. The UN2 threatens nuclear extinction if their local base is overrun.

History
The history of the United Nations 2 is not explored in-game. It is unclear whether previously established countries continue to exist independently of each other, or if they have all combined to form the UN2. The player only encounters UN2 personnel and Private Military Contractors on missions, neither of which possess any form of national identification, like Flag patches for their uniforms.

Additionally, the reason the UN2 is called the "United Nations 2" and not just the "United Nations" is never explained. The UN2 does have similarities to its predecessor - namely its utilization of white and blue colors for identification, and the serving as a global (and now interstellar) peacekeeping force.

Technologies
The United Nations 2 is the most sophisticated military force in the world. They are capable of cloning on a massive and mobile scale, have achieved reliable interstellar travel, and are in possession of advanced nuclear weapons.

Trivia

 * The player is never introduced to any diplomatic portions of the UN2. Unlike its real-world predecessor, the UN2 in Strain Tactics appears to be a military-focused organization.
