The Masascre of 2490 is an event that occured in the year 2490 in the areas around Boston.
Many see the massacre as the first move of the Insurgents, although they had planned other small attacks in other towns before. This event was known mostly because it was what got the attention of the Boston government.
It consisted of the killing of many people around (but not in) the Boston area to eliminate all possible opposition. The Insurgents were ruthless, killing everyone they came across, including men, women, and children.
The attack by the Insurgents was led by Blake Head-Splitter, who wanted Massachusetts to realize the power of his terrorist group.
