Intrepid Six

Of the Intrepid Six, only Adam is still alive (being the sole survivor of season one), the rest of the group being destroyed by outside influences (i.e. infections) and game motivators, in the case of three of the dead IS members by divide and conquer (killed when they strayed from the group).
