Could Didact/Prometheans from Halo 4 take on the Gravemind/Flood from Halo 3, or would the Flood have had too much of a disadvantage? Wonder how the Prometheans' weapons would have worked against the Flood. The Flood wouldn't have been able to infect them since they're al ldigital, but they did have High Charity and other ships under their control with a lot of bodies already turned into combat forms and pure forms and who knows what other evolutions/mutations, and they'd have access to UNSC and Covenant vehicles/weapons.
