GTASC XI - How it works:
There are two separate but concurrent contests - the Individual and Team Contest run by planting42. This year, the Teams will consist of 3 gamers and the contest lasts for 25 periods, each lasting one week.
GTASC XI Scoring: This year, the contest leaderboard will be based on your TA Difference for the period. TA Difference is the difference between the TrueAchievement score and Gamerscore you have earned during that time - so getting harder achievements is more rewarding!
Eliminations: You must try to keep yourself or your team above the elimination line at the end of the period. Those falling under the line at the end of the period go home empty-handed.
See the GTASC XI Announcement Story for more information, and you can discuss the event in the GTASC XI contest forum.
