320th Hunger Games

The 320th Hunger Games took place on antarctic beaches and were won by District 3's Frankie Switch.

Pre-Game
During the days of training before the games, the District 2 tributes, twins Roma and Remus, staged an uprising in the District 2 Tower. They killed their escort and a peacekeeper, arming themselves with their weapons. The fight lasted only a few minutes before a missile was fired at the tower, leveling it and killing Roma and Remus as well as several other District 2 victors.

The Capitol was horribly betrayed by District 2, and randomly selected two new tributes for the games and didn't allow them any training or interviews before the games.

The Games
The District 2 tributes were killed early on in the games. During the morning of the second day of the games, vicious polar bears were set off on the remaining careers, which destroyed their camp and killed all but one of the careers.

Post-Games
The betrayal from Roma and Remus' attack destroyed the relationship between the Capitol and District 2. There were no more District 2 Victors, and many times they were killed early on in the games along with anyone they allied with.

District 2 was also stripped of its military power, and over the next several years the Capitol shifted its military to District 1. This weakened the Capitols military strength, allowing an opportunity to rebel following the explosive ending to the 327th Hunger Games.

Trivia

 * It is debated whether District 2 planned the attack or if it was done purely by Roma and Remus, but District 2 denies it was pre-planned by the district
