Let's just say that at PAX (I was there; did anyone else from XBA attend?), it was confirmed that 10 new achievements worth an additional 250 GamerScore will be added to Halo 3 as part of the September 25th title update, which may be delayed(?).
Most of the Achievements are related to the Legendary Map Pack, while a few zero Gamerscore achievements called "Vidmaster Challenges" will be added.
Here's the list:
Double Double (25 GS) On a Legendary map, get two Double Kills during any ranked or social match.
Poor Yorick (25 GS) On a Legendary map, get 3 Oddball melee kills during any ranked or social match.
Came...From...Behind (50 GS) On a Legendary map, get 3 assassinations during any ranked or social match.
Defend This (50 GS) On a Legendary map, get a flag melee kill during any ranked or social match.
Flag Dropped (25 GS) On a Legendary map, get 2 flag carrier kills during any ranked or social match.
Road Rage (25 GS) On a Legendary map, get 5 Warthog chaingun kills during any ranked or social match.
Look Both Ways (50 GS) On a Legendary map, get a Splatter Spree during any ranked or social match.
Vidmaster Challenge: Lightswitch (0 GS) Get to the rank of Lieutenant in any playlist in the new EXP progression system.
Vidmaster Challenge: 7 on 7 (0 GS) Enter into any ranked or social playlist with 7 EXP on the 7th of the month.
Vidmaster Challenge: Annual (0 GS) After 9/25/08, complete Halo on 4-player Legendary LIVE co-op, with Iron, and everyone in Ghosts.
theres also 5 10G achievements. new skulls are being added. im too lazy to try and be the first to find, so after about 4 days ill end up going on x360a to get the skulls..
vidmasters doesnt sound hard. ill prolly go for leut first, the 7 on 7 i can prolly get while going for leut. the annual i already have a plan for (and have recently figured out where the ghosts are!)
the others will prolly just come to me, like the flag kills, flag carrier kills, oddball, and double...assassination i MIGHT have to work for
btw to those who are wondering, this will NOT get rid of the katana or security armor. nobody knows if theres new armor already hidden on the disc, in case this ever happened, but you never know w/ bungie..
