1 vs 100 just became You vs Your Gamerscore, as the upcoming game will feature Achievements, Kotaku reports. The game will run in 13-week seasons, with each season allotting 200 Gamerscore in Achievements to gamers that earn them. When a new season starts, new Achievements will be available, adding incentive for players to keep coming back.
This news will surely excite Achievement junkies, since the game will most likely be free to them anyway. If they're a Gold subscriber, that is.
