It was before halo though, and the storyline changes everytime you play it.
AND it was written by Orson Scott Card, legendary scifi author.
I was so pissed to find out the Majesco blew their money on a another game that bombed, so they can't afford to continue the Advent Trilogy.
You basically play as the last human in the universe cause earth is blown up.
It's funny cause
[SPOILER WARNING]
At the end you end up going to universal court and suing the race that destroyed earth.
