I didn't let my younger brother Milan play Halo, or even look at it. Given the Mature rating. Because my ██████-esque puritan father Palith was very horrifyingly Draconian in his religious observances. However, when "The Flood" showed up: i chose to call Milan in to play co-op or cooperative (split-screen multiplayer). So, it's no longer as terrifying.
