Do you need a xbox 360 hardrive to complete the halo 3 vidmaster achiements?

[Dizobay]

Can you do them on split screen or does it have to over xbox live co-op?

 

[Jack]

yes you do

technically no but the other answers are on the right track. Im looking at all angles of this question. You dont need a harddrive BUT you need some sort of memory. You need a memory card or a jasper chip (256 mb of space internaly) so that you can have game saves and a gold account. A gold account is required because you need to play the games over xbl.
