Achievement boosters failed back in October to claim the 100-point bounty for being signed in with 1000 others to NBA Live 07. With servers for the game deactivating February 2, they'll take another crack at it on January 31.
Xbox360Achievements.org is once again staging the final run at this damn-near-impossible mark, which appeared in the first achievement-enabled version of EA Sports' hoops franchise and was not carried over to successive versions, for obvious reasons. X360A says "there have been only two times when this has been achieved". They'll try to make it three on January 31, which is a Sunday.
They're trying to get 1000 signed in at 1pm US Eastern (5am AEDT). They promise "multiple x360a rooms set up, with staff and senior members heading up the rooms".
So, if you have the game, or can rent it, steal it or buy it for a dollar-ninety-five from your local bargain bin, that's an easy 100 gamerscore just for showing up. Rumour has it that one person can sign in up to four controllers on the same console and still have it count toward the 1000. X360A has contacted EA Sports for clarification.
