Terminals on Halo 3?

[Jack]

Im trying to get the terminals in halo 3 i went to the 3 in the ark, the two on the covenant and the one on halo but wen i did all of them i didnt get the achievment. I waited till it turned red but i did the levels on easy and didnt finish the level after i got the terminals i also turned my console off before i got the last one. Do u guys no wut i did wrong?

There's 8 terminals in all and you have to start on the beginning of the level and finish to get it.

i think the achivement only works if you start the level from the begining and finish it

There is 1 terminal on the "The Covenant" and one on Cortana's level that you missed.

Just look for them here: http://www.halo3planet.com/terminal-locations/
