In Chaos!!! the setting is post-apocalyptic, though the exact nature of the "end of the world" is left to the gaming group's discretion. Characters have twelve D6 in a dice pool that are distributed among six Traits (Attributes): Fight, Shoot, Scavenge, Mech, Tech, and Heal. Once assigned, dice can't be moved. Characters may gain "Advancement Dice" after a session of play.
