I watched the trailer of Reach on tv. in it the previous noble six member takes a bomb that kat kas armed but cant deliver due to the fact that her hand gets blown off or sumthing and puts it into a covenent carrier and blows shit up and it looks awesome and what not. THEN at the start of halo reach ur the new guy but theres no sign of the covanent on reach and theres no supercarrier nothing. its a blank slate. soooo where was the trailer based??
