USE GRENADES ALOT. Make sure there is always cover around you. NEVER rush in. Sniping enemies out with the sniper and or battle rifle is always good.
For the Flood, shotguns, grenades, the brute shot, rockets and flamers are definitely the way to go.
Most of the Flood are Stupid,and you can run right past them..
Or You Can Play Coop

Get a friend (or two) to play co-op with you.

beating that on legendary was a pain. just ummm get a partner that would help alot. but other then that shoot, stay back and shoot. your gonna die so many times you'll just turn it off.
