First Contact War (Earth-2206)

The First Contact War, also known as the Predator Wars, are a series of conflicts between humanity and its United Nations Space Command against the yautja across the Orion Arm of the Milky Way galaxy. The conflict began on February 11th, 2525, following the yautja's attack on the outer colony Dantana, quickly extending through the rest of the Unified Earth Government's space.

Battle of Dantana
On February 10th, 2525, the yautja nicknamed Jungle Hunter arrived on the outer colony Dantana in order to find creatures to hunt, where he found a guerilla war occuring between human Colonial Militia troops against an Insurrectionist cell. After finding the team led by militaman Jim Hopper, the Jungle Hunter slaughtered them all upon deeming them worthy prey, later flaying their skin and hanging them as trophies. Later on, Sergeant Major Avery Johnson responded to a signal Hopper sent before his death, thinking his life had been claimed by insurgents. Leading a team of Marines, Johnson was able to destroy a local Insurrectionist base, but unknown to them they would fall prey to the yautja hunter. For the next two days, the Marines were hunted down and killed by the Jungle Hunter one by one, until only Major Alan "Dutch" Schafer stood. Dueling the yautja in a waterfall, he was able to outmatch the alien and mortally wound him. Before he could kill his enemy, however, the Jungle Hunter activated his cleasing beam, killing himself and Dutch in the process. This marked the beginning of the First Contact War, with both humanity and the yautha gaining the araweness of each other.

Invasion of Harvest
"Citizens of the Unified Earth Government, we don't know what these creatures are, other than the fact that they're not human. We don't know where they come from. We don't know what they want. But they're invading our colonies and emerging to slaughter our species. Our combined forces throughout Harvest have been mobilized to deal with them. I ask you all to remain calm, as you have done through so many years of war. Stay in your homes unless ordered to evacuate, and listen for emergency information on all broadcast stations. That, my fellow citizens, is all I can tell you until the situation becomes clearer."
