[quote][b]Posted by:[/b] J To The Eroen 1. How did the flood survive the Forerunners' action with the Halo rings? [/quote] Because the Forerunners kept them in containment on Halo's and other facilities for research. [quote][b]Posted by:[/b] J To The Eroen 3. Why didn't they make like a billion spartan soldiers? (or at least 100 while halo 1,2 and 3 were happening?)[/quote] Because the Spartan program costs SO much money. Also they trained the Spartan fours during this time. [quote][b]Posted by:[/b] J To The Eroen 5. Why was the whole flood on that planet in the final mission of halo 3?[/quote] Because the Gravemind crashed the flood infested Covenant Holy City, High Charity, into the Ark (this planet you refer to).
