the halo is a re-named alpha2. it doesn't have the race base or core of the alpha 1 has. just go to the armada site, read up on the alpha 2 and thats it.
"I've learned one thing, and that's to quit worrying about stupid things.You'll never remember class time, but you'll remember the time you wasted hanging out with your friends.So stay out late. Go out with your friends on a Tuesday when you have a paper due on Wednesday.Spend money you don't have. Drink 'til sunrise." -Tom Petty
