Bungie have revealed, amongst a few other things, that 43.28% of people with Xbox Live have finished the game using the normal difficulty setting whilst 15.14% have completed it on Legendary. 2.07% of players have unlocked the complete 1000 Gamerpoints available in the game.
The developer also shared the knowledge that 8.68% of Halo 3 players have managed the Marathon Man achievement, which is gained by finding and using all the Terminals in the game’s main campaign. Which is a lot of hard work.
Apparently there’s also to be some kind of big news today, well Bungie say so anyway. "Folks are definitely going to want to check back in here at Bungie.net and keep faces pressed to their monitors like children breathing on school bus windows in November, because there will be news".
